Well I'll say it, I'd be downright excited. Thigpen quite possibly has tremendous upside. Let's bring him in and make the three of them fight it out (Trent, Brohm and Thigpen). If Trent wins that show down then next year would truly be make or break for him.
If one of the other two lights it up then great. . . we found our QB of the future.
At the very least, one of the three QBs should be good enough to be a back up QB.
Most impotant, Thigpen in '10 means we can focus on using our #9 on an OT this year-- And worry about the franchise QB next year IF NEED BE.
