Cleveland Browns running back Trent Richardson believes he is most responsible for the leagues newly imposed rule penalizing players for using the crown of their helmets to make forcible contact with a defender outside the tackle box. "I feel like I made it bad for all the backs," Richardson told The Cleveland Plain Dealer on Thursday. "I feel like it's my fault."

A video of Richardson knocking off Eagles safety Kurt Coleman's helmet was used as an example of plays the league wanted to penalize during the NFL owners meetings in Phoenix. The rule change passed 31-1, with the Cincinnati Bengals being the only franchise to vote against it.

Richardson told the Plain Dealer that people are starting to name the rule after him. "People keep telling me it's the T-Rich rule," he said. "I guess I made history today."

The penalty will be 15 yards from the spot of the foul, and if both the offensive and defensive player lower their heads and use the crown of the helmet to make contact, each will be penalized.
