Without question.
Yes. Two reasons.
1. He signed with the school, not with the coach. This plays out regularly throughout the country. Kids are not allowed a free transfer when their coach leaves. The school pays for the scholarship, not the coach. They might think they are signing up to play for a coach, but they aren't. They are signing up to play for a school.
2. It is not the ADs job; it is the head of the basketball program's job. They didn't have one? Well, they did ONE DAY LATER. What the hell was the rush for on Tegue's part? What cards did Ellis hold? Answer: None. He should have been told he will need to wait a few more days (at most).
My example was, obviously, extreme to illustrate a point. Whatever the answer is for 7 players, in my opinion, is the same for one.
We can agree to disagree, but I think Teague, if he granted the release as reported - and without consulting Dick Pit - made a huge mistake.
