Because of players like Brock Jacobson. The only reason Wayne wanted him to walk on was because of his 4.0 GPA. If you'll re-read my post, you'll see that I stated that we've turned the corner APR wise. But it did affect recruiting early in Mac's tenure, especially when everyone transferred out and he had to sign a lot of players in a hurry. The players I'm talking about are the ones who decided the semester was over after their last tournament game in their final season and yes, Tim got that ball rolling and handed it to Larry, who handed it to Wayne.
And the fact that all of those players in that first class transferred, or were kicked off the team had as much to do with this excuse as anything Morgan's players leaving did. The same with his second class, and his third.
I am too tired of this argument to go through the list, but Mac has had more turn over than Morgan did. I understand that it's convenient to blame this guy FOUR YEARS LATER, but it isn't true in this case.
As far as players stopping going to class after their last season is over, that is an NCAA epidemic. There are many examples at many schools.
