when you get better recruiting, you usually get more thugs. It's just the nature of it. The vast majority of elite players seem to have violent, sometimes criminal activity. We seem to be getting better players. It makes sense.
That can be said to be the case in basketball where many city kids play in summer leagues and money games sponsored by gang-affiliated organizations. These kids start playing money ball at 12-13 y.o. and their mentors there steer them towards certain schools and coaches, while providing them with game clothes, shoes and money. It's been going on since Connie Hawkins and Earl Manginault dominated the playground leagues in the late 50's-early 60's, and likely long before.
Basketball is a city game and city rules apply. A very high percentage of top city recruits have been playing for money for years before they get to college. A lot of them are supporting their families at a young age through money ball. It's why one and done is so popular. The family needs to eat.
If you've never heard of Manginault, he's the only guy to ever block Kareem's skyhook. Earl was 6'3", Jabbar, who was then Alcindor, was a foot taller. Happened at a summer game in Harlem when both were getting out of HS. The Goat was the Man in NYC and everyone knew it. Played about a half season of pro ball, he was a heroin addict.
Football is different, no summer leagues, no shady AAU coaches, just camps. The kid's are harder to get to. The hinky stuff doesn't really start until college recruiting begins in earnest. Two, football players are harder to id early. That big fat slow kid at 12 or 13 may mature into a monster D.E or he may just be the kid who's future is to be thrown out of Golden Corral for eating all the food? You're not going to have a real handle on him until he's about 15. The speed guys are different, but again, the way football is set up, they're harder to get to.
HQ basketball players are easier to id at an early age. If you've got a skinny 6'10'' 14 year old and you're a crooked AAU coach, that's a product for sale. You can't teach height, you can teach him to play the pivot. Prep school pays for him first, then the colleges. If he's good enough he gets to NBA or plays overseas, and you get your piece. It's a dirty business and it happens at every school in the country. Everyone looks the other way and acts shocked when it surfaces. It's the biggest load in college sports.
