Richard Sherman and Josh Norman, never afraid to speak out, are blasting the new NFL rule that will penalize a defender 15 yards for lowering a helmet into an offensive player.

"It's ridiculous," Sherman told USA Today. "Like telling a driver if you touch the lane lines, you're getting a ticket. [It's] gonna lead to more lower-extremity injuries."

Roger Goodell promised Wednesday that the league will spend the offseason educating players on how the new rule will be enforced.

"I don't know how you're going to play the game," Norman said. "If your helmet comes in contact? How are you going to avoid that if you're in the trenches and hit a running back, facemask to facemask and accidentally graze the helmet? It's obviously going to happen. So, I don't know even what that definition looks like."
