Cleveland Browns running back Trent Richardson said his hit that knocked off the helmet of Philadelphia Eagles defensive back Kurt Coleman was apparently Exhibit A for the competition committee in adopting the rule that will penalize backs who lower their heads and lead with the crown of the helmet.

"I feel like I made it bad for all the backs," Richardson told The Cleveland Plain Dealer . "I feel like it's my fault."

The new rule passed 31-1 with only the Cincinnati Bengals voting against it. Many running backs, including Richardson, have voiced their concern with how the rule will be interpreted, something that can lead to a 15-yard penalty and a fine.

"I know why they did it, but I won't say that I fully agree with it," he said. "I'm not saying it's a dumb rule, but the backs are all talking about it and it's kind of hard on us."

But  in the new safety-conscious NFL, Richardson and others had better get used to it, because it doesn't appear to be going away anytime soon.
