We are combining tidbits of fact with a lot of conjecture here. We know CRod has legal problems. We don't know what the implications will be. Most of this stuff is heresay and conjecture.
Mark Stoops has been at Kentucky since 2013. This is not the first time a star player has been in a pickle. Jason Hatcher, Lloyd Tubman, Jordan Jones, EJ Price. There have been injuries and illness. Nick Haynes, Drew Barker, Landon Young, Chris Oats, Keaton Upshaw, Vito Tisdale. When a player is not available, next man up.
Running back is a deep position. There isn't another running back as good as CRod, but there are a lot of good running backs. Some are better pass receivers or less mistake prone than CRod. If CRod can't play, he would be missed. But Smoke, McClain, Drennen, and Wright would be a formidable rotation. Or maybe CRod will resolve his legal issues. Either way, Stoops will still bring out the best in his team and we can hang in there.
