He's an erratic gunslinger who has a knack for making at least a couple of boneheaded plays a game. He will make quite a few plays and have quite a few big regular season games. But overall, he's unreliable.
He's the type that can win games but will also singlehandedly lose several games. He's definitely not a "big game QB".
And in order to actually win a SB, you have to win at least 3-4 games in a row in do or die situations and I don't see him being able to string together that many error free games in a row, especially in that kind of atmosphere. And in the big games, when it starts going bad for him I've noticed he seems to mentally go in the tank.
With all the scrubs we've had since Aikman, he's definitely the best we've had since then, but I think we'll have to have a much better team, especially defense for us to win any kind of championship with him.
What's ironic is it's been said taking a QB high in the draft and missing on him can set your franchise back several years. But look where we've been by not drafting a QB high since Aikman in '89, other than the reach for QC.
The philosophy that it's better to rely on journeymen QB's, castoffs or undrafted FA's rather than draft one high is mindboggling to say the least.
