At the end of things more education is always a good thing. But athletic and academic opportunities are not necessarily intertwined. The excessive number of years of court ordered eligibilities is a two edged sword, if someone gets 6 years of eligibility someone else is missing out on those opportunities. Makes as much sense as telling a high school freshman, hey in a couple more years after senior JR Doe finishes up his athletic college prep playing for the HS team we will let you play.
Giving a 6th, 7th, 8th or 9th year of college athletic eligibility seems silly. With the money involved walking away from college athletic opportunities is going to get harder and harder and court battles will become more frequent.
