Actually, the league is probably worried about all the players that have been injured and permanently disabled and are just beginning to enforce rules that have been in place for a while. The brain injury thing isn't done yet and the NFL, try as they might, may not be able to prevent many, MANY former players from suing with liabilities into the many billions.
There's a lot of 'fans' that champion the idea that the NFL should be a gladiatorial game with a constant flow of new players to replace the ones crippled or killed. We've even had the idea of the NFL as gladiatorial game mentioned right here in this very thread. But, just so we're know what we're talking about here let's review:
Gladiators had short lives and died in violence for the entertainment of the masses.
Are we to expect todays athletes to work for more than a decade to develop there skills, build there body, and dedicate there lives with little opportunity beyond the game only to say to them ... kill or be killed?
There's no reason the game can't live on the skills of the players, why do we need to have so many injured? What pleasure do you get from watching someone knocked unconscious from a blind side tackle? What joy do you get watching someone get there leg destroyed by a low tackle? Should chainsaws be legal?
Lot of sick f's around here.
