I would definitely bring him in for a visit and have him explain all this stuff to me...from his childhood peeps to this failed drug test, put him on the board, put game tape on the screen and have him explain the defense, checks and calls and really see what he knows or doesn't. Have him watch film like Gruden does with QB's in his 'qb camp' and say, why'd you do that? What were you thinking? What did you see here? Who or what were you reading? I think IF you're gonna possibly draft Foster, he's a guy you really wanna get to know and have as good a feel for him as possible so you know where and how to value him.
