Blame the players on this one guys.
For the NFL its embarrassing when you have a player doing some stupid dance in the backfield because of a sack, while the other team is lining back up to run a play, so here's this little fat DL racing back behind the LOS as the ball is being hiked.
Blame the stupid 4th WR who wants to do some silly celebration because he caught a meaningless TD in a blowout
Blame the idiot LB who lays out a RB with a blind side hit then dances like an idiot because he made a tackle 5 yards down the field on 3rd and 4.
Blame the players for putting the ;eague in the position where they have to punish everyone, because players don't know how to respect the game and the other players. The celebrations by some (not all) players on simple routine plays have just gotten out of hand, and forced the league to take action.
Call it the No Fun League, but at the end of the day, the players brought most of this upon themselves, and they can start there blame with the kings of stupid Chad Johnson, and T.O
