Really? Please list these "misses."
I'm bored so I'll take a run at mid-major hires in the last few years:
Nate Oats (Buffalo to Alabama)-- Has Alabama in the Top 10, seems to be a great hire.
John Brannen (Northern Kentucky to CIncy)-- So-so last year, very bad this year.
Mike Young (Wofford to Va Tech)-- .500 last year, 10-2 and ranked currenty.
Kyle Smith (San Francisco to Wash State)-- .500 last year, bad this year, but it's Wazzu so he always had a tough hill to climb.
Dan Hurley (Rhode Island to UConn)-- Seems to always hover around .500. Not done a terrible job but not a great one
Archie Miller (Dayton to Indiana)-- Given Indiana's history and resources this one would likely be characterized as a disappointment.
Kevin Keatts (UNC Wilmington to NC State)-- Started off ok but has gotten progressively worse. Probably on the hot seat after this year.
Will Wade (VCU to LSU)-- Has had some success, but not without scandal.
Chris Beard-- Success goes without saying
Mike White (La Tech to Florida)-- Has had some good years and disappointing ones. Hard to really go either way on him.
So based on just these I'd say 2-3 were homeruns, the majority have been so-so, and there's been a few duds.
