Unreal, but also not surprising.
Here's how you fix it.
DEATH PENALTY, hardcore, make it hurt bad, make it hurt so bad deep in the heart of Florida that schools in the SEC, ACC, anyone recruiting Florida is scared to death of having it happen again/cleans up any loose ends ASAP.
Make it hurt so bad that schools hire teams to oversee players off the field at all hours of the day, in all places.
Pay the players enough to be a normal college kid, not tons of money, but enough to hang out with friends comfortably, live a typical college existence comfortably.
Get the NFL involved, players that cheat in college get automatically penalized monetarily at the next level.
Make an early signing day for recruits, the longer they hang in the wind, the better chance for under the table crap.
Extreme, yes. Over the top, yes. It's the only way this is going to change.
Does the NCAA have the nuts to take this on? I'm going to say no.
Prediction: USC like slap on the wrist for Thug U, problems pop up in 5 years again.
And don't give me the 18 year old kids don't know right from wrong. I coach HS kids, they are smarter than most adults, they can make stupid choices, but they know right from wrong. Not an excuse.
