In your world, apparently "discussion" = "whining", "bashing", etc.
I hate to tell you this, but I think the Bills have already figured out that turnovers are one of their biggest problems.
You seem to be confused between last year and this year. The Bills did NOT have a good defense last season. They had crappy OT play all season long that was exacerbated by injuries along the interior OL. They had 1 quality NFL caliber WR. Then their best RB broke his leg. In other words, Fitzpatrick was NOT in good situation at all last year, and being the competitive guy he is, he tried to make up for team deficiencies himself. Oops. Not the best idea he ever had, but just about every NFL QB put in the same type of situation winds up doing the same thing. One of the reasons these guys are NFL QBs is their drive to win.
Last year, however, is NOT this year. This year, hopefully, the defense
will be better, but we don't know that. Hopefully, the kids on the OL will come through and make it better, especially at the OT spots. Even if Graham doesn't catch a lot of passes, catching a few big ones will make the Bills passing game better by forcing the safeties to play deeper to guard against the long ball or the long catch and run. Fewer injuries would be
really nice.
On paper, the Bills have improved, but we don't know how that's really going to translate to the field. That's why they play the actual games. If all of the "paper" improvements turn out well on the field, then I expect that not only will the Bills have a winning record and possibly make the playoffs in 2012, but Fitzpatrick will have a great year.
I don't believe in the myth of a QB "carrying a team on his back". If that was true then Dan Marino and Peyton Manning would be sporting SB rings on most of their fingers. Instead, guys who were/are not nearly as great QBs sport multiple ones.
