If it was good enough for football's greatest running back, NFL owners figure, it should work in the 21st century.
Team owners passed a player safety rule Wednesday barring ball carriers from using the crown of their helmets to make forcible contact with a defender in the open field. Pittsburgh Steelers President Art Rooney put the change succinctly.
"Jim Brown never lowered his head," he said with a smile. "It can be done."
And according to the rules, it must be done beginning this season.
The second significant player safety rule passed this week to help protect defensive players came with much debate. Several coaches and team executives expressed concern about officiating the new rule, but Commissioner Roger Goodell championed it and it passed 31-1. Cincinnati voted no.
On Tuesday, the league took the peel-back block out of the game.
The changes were the latest involving safety, and head injuries in particular, with the issue receiving heightened attention amid hundreds of lawsuits filed by former players claiming that the NFL did not do enough to prevent concussions in years past. League officials have defended the NFL's record and did so again on Wednesday.
The tuck rule, one of the most criticized in pro football, was eliminated. Now, if a quarterback loses control of the ball before he has fully protected it after opting not to throw, it is a fumble.
Video review now will be allowed when a coach challenges a play that he is not allowed to. But the coach will be penalized or lose a timeout, depending on when he threw the challenge flag.
