Every team has 53 roster spots and there's 32 teams throughout the NFL. (Weird coincident that theres 32 teams and 32 players arrested!)
Also assume that each offender had a spot on the team and the team has not yet replaced them.
So, 32 out of 1,696 players. That's just 1.89% of the league. If that bad or is that good? I looked into the CIA World Factbook for some comparisons
- Apparently that is the same percentage as American children being under 5 and overweight (1.3% in 2004).
- In 2011, the real GDP grew about that percentage (1.8%)
Anyways, according to the FBI's crime statistics, the NFL is actually doing better than the average. Following Wikipedia's chart, there were 2.9 property crimes per 100 people and 0.4 violent crimes per 100 people.
That's sort of good. If they were above average, action better have been taking place. Thinking about it, a large source of crime is poverty. Some of these guys did find there way out of poverty through football. A lot of their friends and family are probably still living near poverty, making them risk it all by association and eventually making some terrible decisions. Being the rich one of their communities, they might feel like they are above the law as well.
It however could be bigger than this. It could be a from the constant head pounding they have done, the aggressive nature of the game, or the extended down time.
Concussions have been known to cause violence. There's plenty of scholarly articles enforcing that (one example). Football players get concussions almost every time they strap up their helmets and have getting them since they were 5 playing Pop Warner and the liking. Having 20 years of concussions building up for a 25 year old, of course there is some effect from them all.
Football is a violent sport and can totally be depicted as a dog-eat-dog game. The more vicious you are play after play, the bigger your ego is, the bigger the paycheck, and the more likely you will take this aggression off the field. I am not saying all the crimes were violent ones, but it would explain the some of the violent ones.
Preseason starts in August and the regular season ends in December. There are 8 months that these players have to deal with. Yes, they work out, study plays, do commercials, do some charity work (maybe), and work some camps. There's obviously a lot of down time still! More games isn't quite the right solution, but it might help.
An interesting solution is space out the games a bit more. Having a game every other week might be too long, but a week and a half should be plenty. Imagine if every night there is a football game on. I think we are going to see a solution like this sooner than you might think.
Having less free time, more time in between games, and maybe even more games could help this issue. It would make football a full time job for more than just the coaching staff.
