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.
