Schedule: Practice starts today
What’s new: The cornerbacks. Brian Jackson and Dom Franks are gone, but they'll be replaced by some combination of Demontre Hurst, Jamell Fleming Gabe Lynn or incoming freshman Tony Jefferson.
Key battle: The two linebacking spots alongside Travis Lewis. Oklahoma has lots of talent on the defense's second line, but sophomore Ronnell Lewis and redshirt freshman Tom Wort will try to hold off the more experienced junior Austin Box and sophomores Daniel Franklin and Jaydan Bird for the starting spots.
New on the scene: Wide receiver Kenny Stills. The early-enrolling receiver made a splash in the spring and will try to to challenge Dejuan Miller as the No. 2 receiver opposite the conference's best, Ryan Broyles, in the Sooners offense.
Breaking out: Left tackle Donald Stephenson. The 6-foot-6, 285-pound junior sat out all of last season because of eligibility issues, but Oklahoma coach Bob Stoops raved about Stephenson throughout the spring and continued to do so at last week's media days. Stoops says he has comparable talent to last year's left tackle, Trent Williams, who was drafted fourth overall in the NFL Draft.
Don’t forget about: Quinton Carter. One of the conference's hardest hitters, Carter will return for another year patrolling the secondary at free safety. Jonathan Nelson, Marcus Trice and last year's starter Sam Proctor give the Sooners great depth on the defense's back line.
All eyes on: The sidelines. Oklahoma's star power spent most of the season there last season with Heisman winner Sam Bradford and All-American tight end Jermaine Gresham forced to watch. Common sense says it can't happen again, but any more serious, impactful injuries would be increasingly frustrating for Oklahoma.
Quoting: "I really believe, going through a year ago, losing the number of seniors that we did, that we gained experience that you didn't want at the time. That will definitely give us -- make us a better and stronger team coming into this year. More experienced team maybe than we would have been." -- Oklahoma coach Bob Stoops
