I think it is fair to say you can't expect him or anyone to do well with our offense, but I don't think that's intentional on anyones part (which is where I disagree with you, because saying he was "set up to fail" implies intent - I don't think there was, just lack of faith in him).
Oooh.. rephrase then, sorry. I just believe that Fox n company poo the bed this season with their coaching, and the lack of change has finally completely and utterly caught up to Fox this year. Didn't mean to imply he was grinning like a madman thinking of how he could fug this team over or anything as such, lol.
I'd like to believe that Fox wants wins as much as any of us do, but between his stubborness and Davidson's lack of "inspiration" (I guess that would be a good way to term it...), the playcalling hasn't been up to snuff enough to allow our offense to do anything but suck this year. That's what I meant by "set up to fail." Incompetence has bred ineffectiveness, which has led to backbiting, disharmony, and general nastiness from both the fanbase and what appears to be starting on the team as well. EX: Moore's actions v. Rams, Stewie's comments on "holes" in the line, etc.
Basically, the calls aren't getting it done, which leads to players not getting it done, which leads to the team not getting it done. The only thing that has gotten done this year, is the ending of our season, imo.
