Evidently I was wrong with this assumption, but I was under the impression that a recruit could back out of his/her LOI if the coach that recruited him/her was terminated. I read something about it, when Cravens was let go a few years back. Supposedly, Joe was bringing in a guard that was Boyettelike and that the kid decided to go elsewhere once Joes tenure at Weber ended.
Also, if an athlete has yet to use his/her redshirt, why can't they enroll somewhere else and then just sit out a year? Also, doesn't he have the option of not enrolling at any school for a year? If I was Mills, I'd tell Boise where to stick it and go somewhere else. I'm sure he would win back another year from the NCAA if it came to that.
The Boise AD is acting like an idiot over the matter. Granted, Mills is a huge recruit and you don't want to lose him, but, at the same time, you will lose more recruits throughout the Department, not just basketball, if you continue to act defensive. Parents, students, and athletes will see the actions of the AD and decide that Boise isn't an honorable school, and will decide to go elsewhere.
