Gordio, it's like that line from Charlie Wilson's War - "Mr. Wilson always says, 'You can teach 'em to type, but you can't teach 'em to grow breasts!' "
I think you & FLbillsfan#1 have both nailed it - JP had no brains, Trent has no balls.
JMO, but I think the 'brains' part can be taught - put JP together with a coach like Coughlin (or like, oh, say...Mike Leach) for a year or two, and he can be taught better mechanics, to read defenses more effectively, and to make better decisions. Give him an offensive game plan that makes sense, and a set of WRs like Evans and Owens, and - with his arm - the guy will kill opposing defenses.
But how do you teach a guy to have 'heart'? How do you say, "OK, on this next play, you grow a pair of balls!"???
I never liked Edwards, and made no secret of it. Always thought he was a wuss. If you're gonna draft a Stanford QB, it better be the overall #1 pick of the draft - like Plunkett, or Elway.
I think JP will come back to the NFL and surprise a lot of folks. Again, JMO.
