I'm going to steal rodo's list and work from there:
Tier 1: "I really doubt they leave their current school but you gotta call and ask"
- Tommy Lloyd
- Dusty May
- Matt Painter
- Todd Golden (personally, I'd have him off the board anyway for personal reasons, but I understand if others don't)
Tier 2: "The top realistic targets"
- TJ Olzeberger (my personal choice)
- Nate Oats
Tier 3: "Minor potential concerns but still good hires on paper"
- Brad Underwood (too old?)
- Fred Hoiberg (How lasting will his success at Nebraska be, and does he still really want the NBA?)
- Mark Byington (can he be elite, or just consistently very good?)
- Ryan Odom (would really love to see another good year at UVA first)

IMO Brad Stevens is 1A above any of rodo's Tier 1. Obtainable? Likely not. But he's a slam dunk. Tommy Lloyd is 1B. Dusty May is a clear 2 with Painter at 3. Todd Golden is an absolute no for me. TJ and Nate are both a clear step down to me... I'd call them 4-ish. High risk, potential high reward... similar to the risk we took with HD. Would prefer we don't go there. I don't like Oates, so for me the options end with Painter, but TJ is worst case scenario if we are determined to fire HD and move on whether we get better or not.
