I voted undecided on the poll, because in my mind it's not so much a question of whether there's enough criticism being leveled as much as it is a question of "are the right players being criticised?"
Some players, for instance, are criticism magnets. People feel a deep-seated need to criticize these players, rightly or wrongly (99% of the time wrongly) for some offense that these players committed 2, 4, 8 years ago against some team they followed. Players like this are Ron Dayne (that "useless turd" who will "never amount to anything" who somehow managed to become a top-10 RB once they finally featured him in Houston) or Jake Plummer ("Jake the Mistake", the walking turnover waiting to happen who somehow managed to post the lowest INT% in the ENTIRE NFL in 2005). For some reason, it has been decided that these players are worthless, and that designation has become so deeply ingrained that most people are resistant to the idea that maybe it's time to re-evaluate. Heck, Jake Plummer put up three straight pro-bowl caliber seasons in Denver, and yet people STILL seem to believe that he's one of the bottom 5 QBs in the entire NFL.
Other players are somehow Teflon, immune to criticisms of any kind. In fact, even SUGGESTING that these players might be criticisable is often enough to gather a rather large mob brandishing pitchforks and torches. Players like this are Terrell Owens (that "incomparable talent" who caught a lower percentage of passes than Terry Glenn last season, and still managed to post a lower ypc, to boot) and Chris Chambers (who before last season was seen as a near-mortal lock for the top-10, despite the fact that he hasn't had a catch% north of 50% since his second year in the league). For some reason, it has been decided that these players are the bee's knees, and anyone who thinks otherwise is an idiot wrapped in a moron wrapped in an imbecile.
There are players who fall at neither extreme- guys for whom every thread devolves into a jumbled mass of rational discourse and reasonable disagreements- and that's what I value most about FBGs. This message board has the highest percentage of players in the "Rational Discourse" zone than any other board I've seen (with, of course, CBS Sportsline falling at the opposite end of the spectrum). I don't think there is any problem at all with the amount of criticism that these players receive, or don't receive. The big breakdown comes in the form of the Criticism Magnets and the Teflon Men. People need to open their minds on some of these players and realize that they might not be as bad or as good as they thought they were.
