The 2013-14 Oklahoma football team will rely on several key players to deliver on a weekly basis.
Amid the numerous personnel losses, the Sooners may even be pinning their collective hopes on these select players.
Offensively, the greatest uncertainty is at quarterback. Blake Bell, the heir apparent to Landry Jones, needs to make Sooner fans forget about his inexperience by adapting quickly.
Defensively, linebacker Frank Shannon is tasked with resurrecting the linebacker corps and infusing the defense with tenacity.
These are two Sooners who figure to be major X-factors next season. Their success is certainly possible, but uncertain. Additionally, they will be counted on as leaders and play key roles in Oklahoma's success as a team.
The combination of the uncertainty of their success and their importance to the team warrants their inclusion on this list.
Bell and Shannon are just two of OU's X-factors for next season. Read on to find who joins them on the list.
