It isn't a sad day at all. It is something fans have complained about forever. Get fired for anything but losing and you will find a job. Finally shedding some light with actual players and dollar amounts. The NCAA will have to respond. The sad part is that it won't stop the cheating. This might, however, slow it down. If the FBI arrests family members that took money, that will make future players think twice.
The problem is that AAU is so incredibly dirty and corrupt. Has been for a very long time. The shoes companies started fighting for players and teams and so now, coaches found a way to indirectly buy players and stay clean. I hope the FBI goes after the AAU and goes after as many cheating coaches they can. I imagine the head coaches will be implicated in order for the ACs to avoid major time.
I really hope the NCAA takes the opportunity given for reform. I can't say it enough. Switch to the same rules in football. Once you sign on, it's 3 years. You can go directly in though. Get rid of the massive talent disparity and reward good coaching. That would really help Purdue. It would also make the game more fun to watch. I hate the powerhouse teams like Kentucky, Kansas, UNC, and Duke loaded with kids that shouldn't be playing collegiate ball.
