If Groce does indeed go...
Some suggestions...
Darrin Horn...
even though he didn't survive the brutal SEC-East (UK, Vandy, Florida, etc.)...he took Western Kentucky to the sweet 16 and was an assistant at Marquette and played at UK. He's still young and South Carolina is a "football school" where Steve Spurrier casts a long shadow...the are also the 2-time back to back baseball national champs.
Rick Byrd...
may not be "young enough" at this point in life but has taken Belmont to a number of NCAA tournaments...quite a feat since they were playing NAIA ball against tiny schools until not that long ago. (I was roundly flamed when I posted he should have been hired instead of Tim O'Shea back then...looks like I was right and dozens were wrong - sorry to have to bring it up)
Rick Stansbury...
another SEC casualty...had ten 20+ win season and still was shown the door... Had 23+ wins seven times.
Tim Jankovich...
Four 20+ win seasons out of five at Illinois State. Was also an assistant at:
Kansas State (asst.)
Texas (asst.)
Colorado State (asst.)
Baylor (asst.)
Oklahoma State (asst.)
Vanderbilt (asst.)
Illinois (asst.)
Kansas (asst.)
