Are you just messing with me? It's OK if you are, I'm just watching football and hanging out. If you're serious, then I don't think you understand how redshirt works. For one thing, he won't be here long enough to get a redshirt. A redshirt is something you apply for AFTER the season and not before.
He was using "redshirt" in the sense that he would be on the team but not play. He has also stated that he would play if they needed him to. He's going to play at some point, but it won't be until all involved are OK with it. Cal can't force him to play. Cal won't keep him from playing if he and Sharpe agree he's ready.
As I said, when he decided to come to UK, CJ Frederick was a proven commodity who was going to play a large part on our team. Since that changed, Sharpe's decision not to play this year may have changed as well.
