The NFL is a not a PG-13 production.

It is full of sacks and violence and that is one of the reasons why it is one of the nation's most popular sports.

But the league is worried that things have gotten out of hand. Or to be more accurate that the violence has gone to players' heads.

Concussions and players laying prone on the turf has executives thinking about penalizing players with suspensions.

The Steelers' James Harrison, who knocked two Cleveland Browns out of last week's game, speaks for a lot of players when he says he is not trying to injure anyone, but "I'm not opposed to hurting somebody."

Dunta Robinson of Atlanta hit Philadelphia's DeSean Jackson so hard that both players were knocked out of the game. Eagles coach Andy Reid said it was "like a Rocky movie."

That thinking and type of play might come under some scrutiny soon.

Ray Anderson, the NFL's executive vice president of football operations, said the league might start suspending players for dangerous hits stating that "it's our state of mind to protect players." Those suspensions could start this week.

Will this be the same game if gladiators aren't gladiating?

Considering that the NFL still rules the ratings war, should the NFL be legislating hits or will that water down the game for you?
