Justin Haire I'd add in as a stand-up double. 5 straight conference titles, 4 of 5 doubled as tournament champs. 5 straight regionals. Going the small school route he'd probably be my top choice aside from someone like Cliff Godwin who I assume just won't leave ECU.
Jim Penders (if he would leave UConn) would be a homerun hire. Probably a lifer there, though.
I'm not as high on Heefner or Pollard but much higher on Walter. Walter, Rob Vaughn, and McDonnell would have been my top 3 (somewhat realistic) existing college HCs.
Guys like Tulo and Jay are very intriguing to me but totally dependent on who their pitching coach would be. No doubt Tulo can recruit and already understands recruiting.. he'd probably stir up national recruiting to a new level. Jay not so much but he'd have massive pull in south florida because he's so involved and connected there.
