Hmmm... That depends how idiot you consider a fanbase who's team is sitting at 8-7, having not beaten one single playoff team all year, and talking about how they're going to win the next week against their division rivals and 3 other games are going to fall into place... Then, the following week, they're going to beat another team because they have a back-up QB playing (who won pretty easily by the way) and then head up into New England, against a team that beat them easily twice this year, and beat them on the road because we were able to do it this year. After that win, this fan base thought back to when the team played and was beaten easily by the Ravens, and talked about how we could win that game as well, because after all, the team only lost because they were missing their starting center. This fan base even whispered about how their team had held Green Bay to only 9 points last year, so really anything was possible.
This is the same fan base that has hammered the patriots every move for years, but has never seen it's team usurp the Pats in the division, hanging on one playoff win. This fan base mocks the Patriots for going 18-0 and losing the Super Bowl but celebrates itself for almost making it to the Super Bowl two years in a row. This fan base does not see the absurdity in that.
This fan base has spent a good portion of the year talking about how bad a QB who plays an untraditional style is, yet has won games this season, and continues to do so, while at the same time talking about the quality and potential of their own QB who by both statistics and the eye test, is awful, but because he was a part of the team while it lost in two conference championship games, is propped in such high regard.
This is also a fan base who's blamed the bulk of the team's failures this season (and in losses the previous years) on an assistant coach. This is a fan base that gave credit to a consultant while ignoring the easy schedule ahead when he arrived and then quickly forgot that entire argument and that the consultant was still there when the offense fell apart against higher quality teams.
So, I guess there probably could be a more idiotic fan base. Fortunately, the above is all just hypothetical.
Yeah, I was going to answer Jets fans to the subject, but really all fan bases are equally stupid. There were two people who called in sirius nfl on my way home last night complaining about how bad their OC is, complaining about play calls and such, I had to laugh
