You need to re-read the original post. My top option was Chris Beard. Beard is proven. He took Texas Tech to the Final Four. He should be easy to pull away from a low P5 program like Ole Siss. If he says no, only then would I go to the list, starting with Byington. If Byington can turn around Stackhouse's awful pathetic mess at Vandy in one year and turn them into a ranked contender, on top of what he did at James Madison, then that is enough "proven" in my book to tell me that he can evaluate talent, recruit and coach.
That's just it though, Byington didn't do anything with Stackhouse's mess. In the modern world of college basketball, a new coach almost starts from scratch, which is much easier, and in fact, preferable when you can lure in any transfer you can land. Byington has a completely new team. It isn't like he's taking Stackhouse's leftovers and moving mountains with them. That entire team transferred out and Byington brought in 13 entirely new players (11 transfers and 2 FR).
Now, credit to him for making them into a competitive team, but it's hardly proof he can build a program. And don't get me wrong, he'd be near the top of my realistic candidate list, as well, but because I don't think we'll pursue Beard due to baggage, Otzelberger isn't leaving Iowa St. for Tennessee, Bruce Pearl is a pipe dream, etc.
For me, if we are going to aim high, Shaka Smart seems to have figured things out at Marquette and only makes $3 million. His postseason record is concerning, but he's improved by one round each year at Marquette. He may not take the job, but Tennessee offers bigger profile, more money, bigger budget, and a chance for annual revenge against Texas. I'd make the call just to see.
From there, sure, try Beard or Byington, but more realistically...
•Grant McCasland at Texas Tech
•Ryan Odom at VCU
•Mike Morrell at UNC-Asheville
•Alan Huss at High Point
•Griff Aldrich at Longwood
•Ben McCollum at Drake
•Bucky McMillan at Samford
Those aren't sexy names and they don't have piles and piles of success, but they are what the list probably looks like after big (unlikely) names.
Kentucky having to go the Mark Pope route has tempered my expectations.
