The injury bug seems to have been fairly prominent amongst ball-carriers in the Big 12 last season, and unfortunately for Oklahoma, former walk-on-turned-starter Dominique Whaley wasn't immune.
Whaley looked to be on the fast track to a 1,200-yard season until he went down mid-season with a fractured ankle, forcing Roy Finch and Brennan Clay to pick up the slack.
It would prove to be one of a pair of huge blows to the Sooners' offense, as all-world receiver Ryan Broyles would go down just a few weeks later with a severe injury, leaving quarterback Landry Jones grasping for answers without two of his biggest weapons.
One can only speculate, but it's likely that Whaley's absence had a lot to do with Oklahoma sputtering in the final weeks of the season the way they did.
What's important now, though, is that Whaley is quickly getting back into shape and will likely be the starter once the Sooners take the field in September.
If you're a Sooners fan, you have to like it.
The Lawton, OK native rose from complete obscurity to take over as a junior and post 627 yards and nine touchdowns in only six games in 2011.
Whaley is, first and foremost, a hard worker. He runs hard but also has that coveted ability to make people miss, which is something the good people of Norman are used to seeing in their running backs.
With Jones back for his senior year, along with receiving weapons Jaz Reynolds and Kenny Stills, a healthy Whaley would be huge for the crimson and cream in terms of giving Oklahoma all-around consistency on offense.
A healthy Whaley could also mean about 1,400 yards and 12 touchdowns.
That's certainly something to get excited about.
