He's been one helluva nice surprise this year, and has exceeded expectations thus far. But....and this is more my gut than any statistical analysis....I believe of the three (he, RG and Luck), Wilson is more apt to experience a regression next year. Call it a sophmore slump or whatever label you want.
I'm just not convinced he has the raw talent Luck and RG possess in order to be a long term success. Furthermore, I place him in the category of QBs that coaches - having a years-worth of film to dissect - will be able to scheme against with continual success.
He has the heart and drive that any coach would be proud to have in all of his players, but that only gets you so far in this league (ask Flutie). Yes, Flutie had a nice NFL career but he was limited. By extension their coaches are too.
