Tebow is probably going to be used in a few different looks throughout the season. Why else would they pick him up? Hes not playing QB thats stupid.
I actually don't expect him to make the final cut. I think they signed him assuming he'd play for BB and the Pats, he'll do what they ask and maybe learn a new position. And learn that he's very difficult to deal with and as a QB, really does suck..
