Ok I could care less about whether they're on twitter or not, but I'll chime in because I clicked on the thread.
I thought Aaron Williams handled his "tweets" well. Quite well, in fact. Having hundreds of people text you talking crap, presumably celebrating his injury, could bring out much worse in people. I thought he handled it with some class, even if it lacked a certain amount of humility at the outcome of the game. It certainly was not "lashing out at fans."
Fred can say whatever he wants in my opinion, but again, I don't think his tweet was anything worth getting riled up about.
Lashing out at Bills' fans? I think not.
We played a historically bad game. It's gutting. It sucks. But don't look for issues when they aren't there. My .02, for whatever they're worth.
