It's more of a "principal of the matter" stance than what would be in his best interest. Obviously, it would be a pretty selfish thing if a player was even allowed to get away with such theatrics - I don't think it would put him in very good standing with the staff, his teammates or fans. If it was my son I probably wouldn't pass along such advice...
My point is - at some point college athletes need to look out for themselves. His case for eligibility in this case was pretty solid - he hadn't participated in a single official practice, Butler granted his release, Butler endorsed his waiver to become eligible - if the NCAA looks at this case and says we think your still ineligible. I don't think it's that big of a reach for a player to say okay fine - then I will focus on my health, my education, my time etc. etc. until I am eligible. I think college athletes have rights and I think that the NCAA has long taken advantage of those rights for their own benefit.
But... Obviously he shouldn't seriously do that. I'm just talking.
Bump. Look out for yourself argument still in play.
