all i know is that wally did not give a "good game" kind of hug to Jake after the game. It was a long "congrats on a great career, it has been a pleasure to coach you" kind of hug.
also, other players on the sidelines went out of their way to give a him a "good game" hug that they didn't give to the rest of the defense. i may be reading too much into it too. And Jake has proven that he can play through any amount of pain if coach will let him. I think that is why he is being noncommital to saying he is done. Or him and coach being coy to force OU to game plan for him.
