No way. The margin is way smaller than you think.
Accuracy is a wash, deep balls are similar, TT is a better scrambler, but EJ will stay in the pocket long enough for plays to develop. The biggest difference is EJ is better at leading receivers and Taylor is better at ball security. I've seen enough of Taylor to know that he absolutely cannot be counted on late in games, and I think EJ is a gamer.
Of course, at his best Taylor is a little betteroverall, but again, it's a smaller margin than you're making it out to be. Taylor is another one of these QB's, he doesn't stand out that much to me in this playoff-less era. Right now, he's hit a ceiling and I have no faith he can improve. That alone makes me want to see someone else back there.
