You want to say that Trotter suckage is a biproduct of his surroundings, but can't see that his inflated stats aren't a product of having pretty good play makers around him??? As Kaos would say....
Pfffffffffftttttt
Trotter does not complete many balls down field. He gets help from playmakers by throwing short to intermediate routes and lettin the playmakers run free.
I think he sucks and is a liability. Is he the only liability?? Hell no. But to say he is the least of the worries is laughable. He IS the liability on offense.
My point was, he doesn't suck. He's average. With more snaps, which he'd get if the Defense would get off the field, he'd be adequate. If they'd run the ball more he'd be adequate. JMHO, clearly, YMMV. If you say he's the weak link on offense, I might be inclined to agree, but maybe would argue that the OL has been inconsistent, and is a liability at times, and of course affects Trotter. I just don't think he's nearly as bad as you say.
Issues: 1: Defense, far and away, all hell and gone the biggest liability to the team. 2: Apparent lack of identity on offense, and lack of commitment to run game. This is still way far behind the defense. 3: Trotter, which IMHO is a byproduct of the fist 2, and remedying the first 2 would likely improve Trotter.
Again, JMHO, which also includes my trust of Malzahn to have the best he has out on the field, even if it's not as good as he'd like.
