The NFL will do little until the fans take their money elsewhere. They just don't want to admit that they've allowed the sport to become deadly.

He's drawing attention to the issue. Good for him. Now you could say he feathered his nest on football and now he can quit. Maybe so, but he's seen some stuff.

Billy, please elaborate. Repeated hits to the head over many years can't help, but is there a cherry on top?

Billy, very interesting to say the least. Steroids are a big problem and one that has been swept under the rug. I don't recall that the players from other eras, say 1950s and 1960s had that much of an issue. But then, they were not as big physically nor did they play as many games. Steroids have some responsibility for the players being so much bigger today. Collisions are more violent as the playing surfaces are better. How much speed could you get up in a game at the muddy infield of Cleveland Municipal Stadium? So, less games, smaller players and no steroids. Then look at how many games a kid would play until he made the NFL today. Many more collisions over a longer period of time.
