Aside from the fact that we don't know how much or in which direction TT is going to progress over the next 2 years, I think that the comparison you make is dependent on where he ends up. If he is on a team that has great receivers and a good RB, there won't be much basis to compare.
I agree with this.
And now for my inflammatory statement about teblow:
I see him as the same type of player as Heath Shuler. Big arm, not the most accurate passer, good runner, elusive, very VERY good college QB. But an NFL flop. I now apologize to Heath. I've met him personally and he's a really good guy. Sucked at the NFL though.
