We learned last week the NFL Competition Committee will consider adopting a rule to penalize players for the on-field use of the N-word.
"I think it's going to be really tough to legislate this rule, to find a way to penalize everyone who uses this word," Clark said, according to ESPN.com. "And it's not going to be white players using it toward black players. Most of the time you hear it, it's black players using the word."
As evidence for his take, Clark cited an effort by Steelers chairman Dan Rooney to weed the word out of the Pittsburgh locker room.
Clark said the respect the players have for Rooney led to an immediate acceptance of the request.
"Ike went around to specific people and said, 'Listen, this is what Mr. Rooney told me,'" Clark said. "He's the ambassador. We call him Old Man Rooney. He has a lot of respect, and because of the way he has treated us as players, as black athletes, (and) also treated Coach Tomlin as a black coach, you know it's coming from a place of love."
However, it didn't last.
"You stopped hearing it immediately that day," Clark said. "But after a while, it came back because it's the culture. After a while, it comes back because this is what these guys have grown up with."
Clark's point: The proposed rule might be a good idea, but it could prove difficult to regulate.
