Spring answers:

1. Bryce is the guy. It was going to take a lot for Bryce Petty to lose his starting spot, but he looked like a guy who suited up for his fourth spring this year and cemented his status as the heir apparent to a crazy-good quarterback tradition under Art Briles. He'll follow Robert Griffin III and Florence, who both set school records for passing yards.

2. Defense changes its identity. The Bears didn't have a ton of speed in the secondary last season, and as a result, relied heavily on zone and didn't play a lot of tight coverage. To start fixing the problem, Dixon moved back to traditional safety, and as the defense's most physically skilled talent, that was a wise decision. Baylor wants to play more man and play tighter this year, and we'll see if it pays off in the fall.

3. Offense finds its playmakers. Williams is gone and so is Sampson, two of the team's top three receivers. Reese returns, but Antwan Goodley and Jay Lee emerged to win starting spots this spring, and both look like big-time targets for one of college football's best offenses. Count on those guys and Clay Fuller to keep the tradition going.

Fall questions

1. Can the defense prove itself? The Bears were definitely one of the best defenses in the Big 12 over the last month of the season. The same unit, however, was also a big reason why Baylor limped to an 0-5 start in conference 12 play before ripping off four wins to end the season. The defensive line should be improved and young talents like Javonte Magee and Shawn Oakman could make names for themselves this fall.

2. Is the offensive line deep enough? Baylor's history under Briles at this position makes me pretty confident, and the Bears have a solid starting five. But losing Troy Baker this spring is a big knock, and the Bears only had 10 healthy offensive linemen this spring. Come fall, more injuries could force the Bears to force inexperienced players into the rotation. This was probably the biggest concern for Briles all spring.

3. Just how good is Petty? He looks good for now, and was productive and impressive during the spring. That's also the spring. RG3 and Florence broke school records for passing yards in consecutive seasons, though, so the bar is sky-high. There's every reason to believe in Petty, but expectations are high and reaching them won't be easy. The good news is he has a huge talent in Seastrunk and a solid receiving corps around him to support his efforts.

Spring answers

1. The defense's intentions are clear. Bill Young is out. Glenn Spencer is in, and he's all about playing aggressive. Tight coverage and blitzes are the name of the game, and we'll see if it pays off in a Big 12 lacking in quarterback experience. Last season, OSU's parade of turnovers came to an end, but Spencer seems intent on bringing it back. Nobody's stopping Big 12 offenses, but forcing turnover and holding teams to three in the red zone are how you succeed on defense in this league.

2. The offensive line is set ... for now. Center Evan Epstein and guard Lane Taylor are gone, but the Pokes are going with youth at left tackle in sophomore Devin Davis, moving last year's left tackle, Parker Graham, to left guard. Meanwhile, junior Jake Jenkins is sliding up to take Epstein's spot at center. That's how it ended in the spring, but OL coach Joe Wickline is kind of unpredictable, so those guys better continue to bring it in fall camp.

3. Athletic director Mike Holder is still running the show. Gundy and Holder had a disagreement on scheduling that nearly ended with Gundy packing his bags to succeed Derek Dooley in Knoxville. But Gundy's displeasure with Holder helping schedule Mississippi State this year and Florida State next year -- both on neutral fields -- hasn't changed much. OSU just announced a future home-and-home with Boise State. Who knows what Boise will look like then, but the intent is clear: Holder wants attention-grabbing, money-making games to start the season, not home games against patsies to help OSU run up an easy 3-0 mark before conference play begins.

Fall questions

1. Seriously, what's the deal at quarterback? Chelf is the safe bet at quarterback, but Gundy reneged on a statement midway through spring that he would hold onto his starting spot in Week 1 ahead of J.W. Walsh and Wes Lunt. Now, Gundy says the starter for Game 1 hasn't been decided, and quarterbacks are off limits to the media with no updates being given until after the season opener. We'll see if Gundy sticks to it, and if Chelf hangs onto the starting job he earned with strong play to close 2012.

2. Is Oklahoma State a new Big 12 power? The Pokes broke through and won a title in 2011, but one title doesn't mean anything in the big picture. OSU is in position to win another and just may be the league favorite to start the season. They are in my book for sure. Two Big 12 titles in three seasons? That's serious, and the Pokes have a chance to do some special things this season.

3. Is Mike Yurcich the next super coordinator at OSU? Mike Gundy's been a head coach less than a decade, but his coaching tree is already way underrated. He's churning out head coaches year after year, highlighted by guys like Dana Holgorsen at West Virginia, Larry Fedora at North Carolina and Tim Beckman at Illinois. Todd Monken just left for Southern Miss, and if Yurcich, who stepped into the new role from a Division II school, keeps the pace for this offense, I'm betting he may attract interest before too long, too. Watching how he handles Year 1 will be interesting. Monken came from being an NFL position coach and made parlaying that into a head coaching job look easy.

Interceptions: Jason Verrett* (6)

Spring answers

1. Offensive line getting straightened out. James Fry and Blaize Foltz were big losses on the interior of the offensive line, and replacing them was a big concern for the Frogs' quiet spring. The spring ended with senior Eric Tausch atop the depth chart at center and sophomore Jamelle Naff winning the right guard job to replace Foltz. Tausch started at left guard last season and moved over, but sophomore Joey Hunt slid up to replace him. Neither Naff nor Hunt have much experience (Hunt earned his lone career start in a loss to Iowa State), but they'll be leaned on this season.

2. New targets acquired. Josh Boyce and Skye Dawson took their talents to the next level, leaving the Frogs in search of a pair of new starters. LaDarius Brown and Brandon Carter were sure things, but strong springs helped fellow juniors Cam White and David Porter win starting jobs at receiver. There aren't many open gigs for a team returning 15 starters, but that's one that will have a big impact.

3. Mallet dropping the hammer. Junior Marcus Mallet emerged late last season and finished with five tackles for loss and a forced fumble among his 18 stops. Now, he looks like the likely candidate to replace departed Kenny Cain and a possible breakout talent on a loaded TCU defense. The 6-foot-1, 216-pounder finished atop the depth chart after a good spring.

Fall questions

1. Is Casey Pachall back to his old self? It's probably safe to operate under the assumption that Pachall will win his job back in fall camp, but beating out Trevone Boykin isn't the same as leading the Big 12 in passing efficiency, like he was last year before his DUI arrest that ended his season. You don't win a Big 12 title with average quarterback play, which brings me to my next question.

2. Can TCU really handle a Big 12 schedule? TCU was competitive last year, sure, and only had one game that it wasn't competitive in. But TCU's not trying to be competitive. It didn't come to the Big 12 to do that. It came to win, and it's proven exactly nothing in that realm just yet. Managing a difficult week-to-week schedule is one thing. Winning just about every week is another. Ask K-State's 2012 team and Oklahoma State's 2011 squad how easy that is.

3. Is the defense for real? On paper, this unit should be absolutely dominant after finishing No. 1 in the Big 12 in total defense and returning nine starters, including Big 12 Defensive Player of the Year Devonte Fields at defensive end. That sounds like Texas' defense from last year, who fell off the map and allowed more rushing yards than any team in school history. Sometimes, you just never really know. This is a new season and last year means nothing. Prove it again.

Interceptions: Javon Harris (6)

Spring answers

1. Playmakers abound: The Sooners might have lost leading receivers Kenny Stills and Justin Brown, but there’s plenty of firepower back to support whoever wins the starting quarterback job. Jalen Saunders was actually Oklahoma’s most efficient receiver the second half of last season and seems primed to take over as the go-to target. The Sooners also have several talented up-and-coming receivers who had good springs, led by slot extraordinaire Sterling Shepard. The backfield is even deeper, with leading rushers Damien Williams and Brennan Clay back, to go along with Trey Millard, one of the top all-around fullbacks in the country.

2. Cortez will flank Colvin: The secondary was decimated by graduation and Tony Jefferson’s early entry into the NFL draft. One of those voids was cornerback, where Demontre Hurst had started the previous years. That void at least, however, appears to have been filled. Arizona transfer Cortez Johnson seized the job from the first day of spring drills, and has given the Sooners every indication to believe they’ll have a big, physical corner to pair with All-American candidate Aaron Colvin in the fall.

3. The linebackers will play: In a desperate move to slow down the high-powered passing attacks of the Big 12, defensive coordinator Mike Stoops pulled his linebackers off the field. The plan backfired, as opposing offenses ran at will over the linebacker-less Sooners. This spring, Stoops has renewed his commitment to the linebacker, which, ironically, could be the strength of the defense. Corey Nelson, Frank Shannon and Aaron Franklin are all athletic and capable of generating negative plays, something Oklahoma’s defense sorely lacked last season.

Fall questions

1. Who the QB will be in October: Bob Stoops said he would wait until the fall before naming a starter, and so far, he’s made good on his word. Junior Blake Bell took a lead in the competition during the spring, as expected. But sophomore Kendal Thompson and redshirt freshman Trevor Knight, who both got equal reps as Bell, played well at times, too. It’s hard to see Bell not starting the first game. But if he struggles against a tough September schedule, it’s not unthinkable one of the younger QBs would be given a shot.

2. How the new offense will fare: Looking to utilize the skill sets of their mobile quarterbacks, the Sooners will be running a very different offense from the one Sam Bradford and Landry Jones both operated. Offensive coordinator Josh Heupel kept most of these new plays - including loads of read option -- in his hip pocket during the spring game. But it will be interesting to see how the Sooners -- and just as important, opposing defenses -- adjust to this new era of offense in Norman.

3. Defensive line play: The Sooners went into spring ball with just three defensive tackles on the roster, and little experience at defensive end. The unit showed strides during the spring, with Chuka Ndulue making a smooth transition from end to tackle, and tackle Jordan Phillips coming up big in the spring game. But that was the spring. The defensive line will have to continue to grow rapidly in the fall for the Sooners to have any hope of improving from last year defensively.

Sacks: Alex Okafor (12.5)
Interceptions: Quandre Diggs* (4)

Spring answers:

1. Under center: Texas has finally ended all the debate about its quarterback situation and settled on David Ash. While Ash has yet to be stellar in his first two years at Texas, the junior has steadily improved -- he was top 25 in pass efficiency rating in 2012 -- and has won the trust of new quarterbacks coach Major Applewhite. Applewhite believes Ash is the quarterback best suited to run the new up-tempo, spread attack.

2. Loaded at linebacker: One year after being the worst tackling team in the Big 12, Texas went into the spring looking to shore up its linebacker position. And it had plenty of options. Texas has seven linebackers who have started at least one game. Included in that group is Jordan Hicks, who is back after missing 10 games last year because of a hip injury. Hicks will team with true sophomores, Dalton Santos and Peter Jinkens for what should be a much faster and aggressive unit in 2013.

3. Along the lines: While there were a sprinkling of injuries along the offensive line this spring (Josh Cochran and Trey Hopkins), Texas appears to have finally solved the depth riddle at that position. Tackle Kennedy Estelle was able to get quality snaps and should prove to be a solid backup and Sedrick Flowers finally emerged as an option at guard. While Texas returns all five starter from a year ago along the line, the Longhorns know that in the new up-tempo offense it will have to lean heavily on these backups.

Fall questions

1. Speed thrills: Texas wants to move the ball fast. So fast that the offensive players were even taught how to quickly get the ball back to the official so that they could put it down and Texas could line up and run the next play. But Texas only decided it wanted to play this way in mid-December when there was a change in playcallers from Bryan Harsin to Applewhite. So Texas has only had a handful of practices to get up to speed. With a schedule that has Texas at BYU for the second game of the season there doesn’t appear to be much time to get things perfected.

2. Safety dance: Texas’ defense was the worst in school history and that was largely due to the play of the back seven on defense. And now the best player in that back seven, Kenny Vaccaro, is gone. He was a first-round draft pick. That has left Texas wondering who will step up and make some stop at the safety position. Adrian Phillips takes over for Vaccaro, but he was inconsistent last season. The coaches blamed a shoulder injury and the fact he missed the spring. Mykkele Thompson and Josh Turner also missed their share of tackles but both are being called on to be possible starters.

3. Receiving praise: Texas has not had a 1,000-yard receiver since Jordan Shipley in 2009. Mike Davis had 939 yards last year and appears poised to break the 1,000-yard mark this season. But to do that he will need help. And right now there are some questions as to where that help will come from. Texas wants to go with four wide receivers but two of the four players expected to fill those roles -- Cayleb Jones and Kendall Sanders -- are currently suspended because of legal issues. Both will probably be back. But even then, Texas is very thin at wide receiver and needs some other players to step up to help take the double teams away from Davis.
