Yes, college athletics has been ruined by greed. I've said for a long time that cable TV ruined America. Politically, culturally, societally, and in sports too. ESPN particularly has ruined sports.
Personally, as time has gone by and college football especially has gone from a money making sport to a bazillion dollar making sport, I have switched from a "well, they're getting a free education" view of college athletes to a "adults are making tens of millions off this sport, kids need a piece of that pie" view, knowing full well that this will further accelerate the demolition of the sport.
Cable/streaming contracts are ruining the college sports. NIL will further ruin them. The transfer portal will further ruin them. But all of that derives from the greed that cable TV kick started.
