I've loved the production from Stevie the last 6 weeks, but the way he has dealt with the success hasn't been encouraging. In my mind, he's a rookie (1st time he's seen any real PT), on a non-contending team that has put up some great numbers during a small sample period. The haircut, Joker Touchdown and the way he dealt with his mistake on Sunday (sulking in the end zone and on the sideline, God Tweet etc.) all point to a lot of immaturity and a "Diva" personality with a focus on self before team.
I'm sure he bounces back from this. I just hope he does it with his mouth shut and lets his play on the field doing the talking.
