Big 12: LaGrone Shields
Posted by ESPN.com's Tim Griffin
Big 12 defenses are nearly as proficient as their offensive counterparts. But the best teams in terms of defense will likely end up as the conference’s best teams because stopping the high-powered offenses in the conference is so rare.
Here’s a look at how I rank them:
1. Oklahoma: The Sooners return nine starters and are among the nation’s very best defenses. It starts with three-deep talent along the defensive line keyed by Gerald McCoy and Auston English, who was the conference’s preseason player of the year last season before spraining his knee. They might be a little lacking in depth at middle linebacker behind Ryan Reynolds with the injury to freshman standout Tom Wort and Mike Balogun’s iffy status. The only new starters are strong safety Sam Proctor and free safety Quinton Carter, who have both been impressive in fall camp. The Sooners’ substitutes might be better collectively than most Big 12 units.
2. Texas: The Longhorns have arguably the conference’s best back seven, particularly a developing secondary led by Earl Thomas and corners Chykie Brown and Aaron Williams. Sergio Kindle and Alex Okafor are poised to become the primary pass-rushing specialists. Lamarr Houston has developed into an anchor at defensive tackle, but the Longhorns need to find another player at the other defensive tackle position to juice production for their biggest defensive weakness. Will Muschamp’s unit must do a better job after producing only 16 turnovers last season to rank tied for 104th nationally.
3. Nebraska: It all starts with the defensive line, which is among the best in the nation with Outland Candidate Ndamukong Suh and defensive ends Pierre Allen and Barry Turner. The Cornhuskers are young at linebacker where they might start two linebackers, although coaches really like 6-foot-6, 230-pound buck linebacker Sean Fisher and Will Compton. Coaches say the secondary is playing with more confidence, but the group produced only 12 interceptions last season. Boosting that turnover production will be critical in the Cornhuskers’ division title hopes.
4. Texas Tech: This is where the big drop-off starts from the top three teams. The Red Raiders will miss pass-rushing threats McKinner Dixon and Brandon Williams from last season, but have an experienced unit back. Rajon Henley and Brandon Sharpe are set to fill in as the pass-rushing threats and Colby Whitlock can be a terror at times -- particularly against Texas. Brian Duncan is a producer and the team’s leading tackler at middle linebacker. Jamar Wall is one of the better cover corners in the league. But the unit will depend on the improvement of two projected starters: redshirt freshman free safety Cody Davis and strong safety Franklin Mitchem.
5. Oklahoma State: The development by veteran defensive coordinator Bill Young will determine whether this unit has the goods to lead the Cowboys to their first South title and a potential maiden BCS bowl appearance. The biggest key will be producing more sacks from a defensive front that notched only 15 last season. Young has been concentrating on push from his defensive tackles and thinks he has an underrated pair in seniors Swanson Miller and Derek Burton. The loss of Orie Lemon at middle linebacker will hurt, although Donald Booker has been a producer in limited playing time. The secondary will be playing new starters with only Perrish Cox returning. But keep an eye out for senior free safety Lucien “The Punisher” Antoine who was turning heads last season before blowing out his ACL in the second game last season.
6. Colorado: The Buffaloes are faster this season and that should help them cope with the high-powered offenses in the Big 12. The linebackers are deep with Shaun Mohler and Jeff Smart as the prime producers. And I really like the secondary, with Jimmy Smith and Cha’pelle Brown among the best pair of cornerbacks in the conference. The biggest concern is along the defensive line, particularly after the injury of heralded freshman Nick Kasa that may idle him for the season. One area to note will be at right defensive end, where sophomore Lagrone Shields and freshman Forrest West are in the two-deep. Shields has played four snaps in his career.
7. Kansas: The Jayhawks need defensive improvement if they are going to fulfill their hopes of making their first championship game. The Jayhawks were crippled last season without a consistent pass rush. They hope junior-college transfer Quintin Woods, Caleb Blakesley and 304-pound Jamal Greene up front along with sack leader Jake Laptad. After losing three starting linebackers from last season, the Jayhawks will retool. I look for them to play two linebackers and a nickel look in many cases. Look for freshman Huldon Tharp to become a producer at linebacker. The secondary is the strength of the defense with All-Big 12 candidate Darrell Stuckey at strong safety and Phillip Strozier poised to continue his late-season development.
8. Baylor: Up the middle, the Bears might be among the strongest defenses in the conference with heralded transfer defensive tackle Phil Taylor, linebacker Joe Pawelek and hard-hitting safety Jordan Lake. Baylor coordinator Brian Norwood knows he needs more production from a defensive line that collected only 21 sacks and allowed opponents to complete 67 percent of passes for 3,063 yards. Antonio Jones and Antonio Johnson sometimes get overshadowed by Pawelek at linebacker. Junior cornerbacks Tim Atchison, Clifton Odom and Antareis Bryan need to improve or it could be a long season for the secondary.
9. Missouri: Any defense that starts with All-American candidate Sean Weatherspoon won’t be too bad. The Tigers could be a surprise considering that Gary Pinkel has been raving about the speed his unit possesses -- particularly at defensive end and at cornerback. Look for a three-man rotation at defensive end with Brian Coulter, Jacquies Smith and Aldon Smith to boost production in the pass rush. The secondary was a huge liability last season ranking 118th in pass defense. Kevin Rutland has shown a physical style at cornerback and Kenji Jackson and Hardy Ricks might be ready to help at safety.
10. Kansas State: New coordinators Chris Cosh and Vic Koenning plan to run a 4-2-5 defense. Their first concern is developing a rush with 2008 first-team freshman All-America pick Brandon Harold out with an injury. While he’s gone, the Wildcats need Eric Childs and Jeffrey Fitzgerald to emerge up front. John Houlik and Alex Hrebec apparently have earned the starting jobs at linebacker. Three junior college players -- David Garrett, Troy Butler and Emmanuel Lamur -- have apparently earned starting jobs for a secondary that desperately needs to improve after ranking 106th nationally in pass defense. The defense ranked tied for 110th in scoring defense and 117th in total defense, so the new coordinators better boost improvement or it will be another long season.
11. Texas A&M: Whatever happened to the Wrecking Crew defenses from the past? The best indication of the concern that Mike Sherman has for his defensive unit came when he transferred projected starting left tackle Lucas Patterson move back to defensive tackle late in preseason practice to boost production inside. Von Miller was impressive at the “jack” position, but he’ll need some good fortune to hold up consistently rushing against the huge offensive lines in the conference. The Aggies need to improve after yielding 461 yards and 37 points per game and earning the ignominy of being one of three FBS teams to allow opponents to average 200 yards rushing and passing last season. Coaches say the unit is faster and more athletic, but they have to play much better to get the Aggies back into bowl contention.
12. Iowa State: Veteran defensive Wally Burnham has a great reputation and most recently flummoxed the spread defenses of the Big East while at South Florida. The Big 12, however, will be a different story. The Cyclones ranked tied for 110th in scoring defense and 112th in total defense. Coach Paul Rhoads says he’s been frustrated by his team’s lack of tackling techniques. They have a building block in cornerback Leonard Johnson. Burnham and Rhoads know what they are talking about defensively as both were coordinators for top 30 defenses last year. But it will take a lot of patience to help rebuild this unit that needs so much improvement.

Colorado freshman Nick Kasa will be idled for at least three weeks with a torn MCL in his left knee.
The injury will more likely sideline the Buffaloes' top 2009 recruit for 6-8 weeks, although team officials still hold out hope the injury might not be as severe as originally diagnosed.
Kasa told the Denver Post that surgery remains a possibility, but that also won't be determined until the swelling goes down.
"It's definitely a pretty bad setback for me," Kasa told reporters Wednesday morning as he watched the practice with his injured knee immobilized. "I want to play. I think everybody wants to play. I just have to take it in stride and do what I can to get back as fast as I can."
If the injury stretches out through four or more weeks, a redshirt could be likely for the 6-foot-7, 270-pound Kasa. He was in the mix for immediate playing time after coming into the program as the most heralded addition in Colorado's 2009 recruiting class.
The injury occurred during a two-man pass rush drill when an offensive guard blocking the other defensive player unintentionally rolled into Kasa's left side. Kasa told the Denver Post he didn't see it coming.
"The last week, I really started to catch on to things. Everything was going good in practice," Kasa told the Post. "I've got to be out now, especially for CSU (the Buffaloes' Sept. 6 opener at Folsom Field). I really wanted to play in that game. I just have to stay positive."
Marquez Herrod is expected to be the starting defensive end on the other side. Sophomores Conrad Obi and LaGrone Shields have the inside track for playing time, followed by sophomore David Goldberg and freshman Nick O'Neill.
