From what I see about Clemson football, and same with many programs, is to recognise that college football is just about 75% changed from what it was just 5 years ago. The old model of recruiting from HS, developing players, insisting players get educated, is done.
College football has become a "poor man's" pro league. Now, if you have a problem on the offensive line, you "buy" an all American from a competitor. Heck, if you had enough money, you could just "buy" the entire offensive unit from Ohio state or Texas tech.
Student Athletes...yea, there are some left. But in today's environment a future #1 draft choice could attend four different universities in 4 or 5 years, earn $$millons, and never get beyond sophomore academic standing.
It's a changed world and coaches need to change to adapt.
