You got a point there. No NFL team wants fan(atics)going to the stadiums yelling in the stands, buying tickets, buying T-shirts, arguing about players, plays, and tactics. Next thing the fans will be talking sports at the water cooler at work, posting about the team on Facebook, tweeting, buying advertisers products, reading sports columns and then making comments. No NFL franchise wants that kind of attention from the public. That's why you never see NFL advertising or promotional gimmicks. They don't want the publicity.
There are FANS.
And there are FANATICS.
FANS are not a distraction.
FANATICS obsessing over a single individual, and their fanaticism being a source of distraction and generating negative publicity is a problem. That's what was happening to the Bronco's and the NY Jets.
Then there's the fact that Tebow WAS NOT performing at the level expected of an NFL QB which just made his FANATIC supporters foam at the mouth whenever that was pointed out .....
