Evidently, he thought he was in for another year of it as a true sophomore and wasn't putting up with it. You have to admit, we worked Superman to near death last year. I can still remember him limping back into the game for yet another carry. Very reminiscent of the way we kept playing Helu when he was hurt (2008 or 9?) and TM in 2010.
I'm not sure that Bo is doing that....and the only way Rex would have a shot at Heisman is if Martinez improves markedly in his passing, opening up running lanes for Rex.
Heisman or not, if the other kids don't think they will get a fair opportunity to play and they believe they are as good as Green does, they will leave. We've had a few doing just that lately. Never used to see this sort of thing.
