How do you know that he didn't interview "too many people at all"?
And I will reiterate the fact that every article I read and person I heard, rated Archie as the top hire in college basketball. That isn't just a fluke. RMK didn't endorse him for kicks. He was HIGHLY thought of as a coach and most speculate that if IU wouldn't have hired him he would now be at OSU. All of that said, Archie might not be the guy but the next one or two years will tell the tale.
If he doesn't work out, that IMO, doesn't make it a bad hire by Glass. If you have every hired people, did everyone of them excel? I know I can't make that claim.
