I didn't say he's the best QB in the league & I certainly didn't say he carries the highest QBR.
I'm not going to say he has excellent mechanics & I'm not going to say that you don't have a point regarding the number of teams that offered a trade for him.
What I am saying is, he's not the worst player in the NFL & he is deserving of a legitimate shot at being a starter in one position or another. In fact, I think he could be a starter in more than one position, depending on circumstances (opponent, QB, FB, RB, etc.).
Most folks around here & the media seem to think the guy should retire from the NFL because he's not good enough. I disagree. In Denver, he proved that he's good enough for the NFL.
In the meantime, on a new team, while battling for a starting role, he would also be an asset on short yardage situations. The Jets were supposed to utilize him for this, but decided against it (dumb move). On 3rd & 1, the guy will get a 1st down. The guy can run a lot of people over, but nobody seems to care about that.
To the point on fumbles, sure, he's had fumbles. So has Brady, Peyton, Colin, etc., all during the playoffs.
