6. There are already enough injuries and suspensions to derail this train if they're not prepared
The biggest blows were losing senior center Ben Habern, who cut his career short with ongoing neck and shoulder injuries, and right guard Tyler Evans, who tore his ACL. But the Sooners are now without defensive tackle Stacy McGee, suspended indefinitely for a violation of university policy. Then, there's wide receiver Jaz Reynolds--though with the depth, OU doesn't figure to miss him that much--and defensive backs Trey Franks and Quentin Hayes. Wednesday it became official that defensive tackle Casey Walker could miss the game due to an undisclosed personal issue, neither a suspension or on-field injury. All of this means a number of other players must step up, most notably defensive tackle Jordan Phillips, along with David King and Jamarkus McFarland. Back on offense, it's guards Adam Shead and Bronson Irwin who must elevate their games to help out Gabe Ikard, who shifted over from guard to center. OU clearly has the tools to overcome their injuries and suspensions, but these could also be an issue as well.
