I don't think Holcomb is more talented than Drew Bledsoe- not by a longshot- BUT, I think its easier to field a team around Holcomb. Drew Bledsoe is in the Jim Kelly mold (but not nearly as good). He holds onto the ball, and is willing to take the big hit.
Problem is, defenses are quicker, and hit harder than they did back then. The hits add up, and by midseason, Bledsoe declines.
Holcomb, while not nearly as talented, unloads the ball quickly, and won't take many chances. Therefore, he is the same QB on thge last throw of the season as he was on the first throw.
Holcomb does not require one to spend the whole cap on an offensive line- one that can't block for as long as Bledsoe will hold the ball anyways- Dallas has a more talented group than we fielded with Bledsoe, and the hits are still adding up, and they, like we were, are on the brink of playoff contention entering the final week.
