Of course he's not going to publicly complain after a *win*. Who knows what he said privately? If you're willing to believe he only nursed and fostered resentment over his targets when the team lost, and it was only then that he shared those feelings with Barber and Crayton and Hurd and whichever of his cronies would listen, I'm not sure what to tell you. He was poisonous, win or lose. He paid the price for that and got himself cut. Good riddance, bad rubbish.
The throw to Witten was not low-percentage. But it doesn't matter if it was low-percentage, because his QB hit him right on his Captain's patch. Anything else re: that play is just noise.
It's the background white noise about a QB that we waste time defending when there's absolutely nothing to defend. Then, later, when the QB really does make a game-changing mistake that costs the team a win or a chance at a win, those actual mistakes get all bundled up with nonsense like this thread to give the illusion that there's a problem with the QB of this team and 'not being clutch' (however that's supposed to be measured).
Meanwhile, we gave up 3 TDs, 400 yards, and a 120 QBR again in pass defense, and are a bottom-ten team in that regard again so far for yet another season, and people are wasting their breath on whether or not a pass a receiver had to adjust his body for in order for a pass to hit him square on the numbers was, in actuality, somehow an errant throw. It's just absurd.
