Your sentiment about wait and see on May is fair... but consider this:
Mike Woodson is an IU guy. Yes he was a player, with NBA coaching experience but that is vastly different than May's experience.
Archie Miller was in his 40's. 40s was only in reference to the fact that he could be coaching for a long time.
Mike Davis went to a final 4. With CBK's recruits, it was down hill from there. May built FAU into a F4 team, key word built. With the portal the way it is now, he has also rebuilt Meatchicken in 1 year.
Tom Crean went to a final 4 and won multiple BIG titles. That he did. And, he built IU to a respectable place considering what he took over. It became his relationships with recruiting networks and his scattered over-recruiting approach that brought inconsistency follow by a big trend downward.
