Not that this matters at all, but looking at coaches that have left, I'll say I wish just Jack Gardner and Huggy would've stayed, but the results have been interesting.
Gardner to Utah - A program a little better than K-State at the time, then took them to multiple Final 4's. Pretty damn solid results.
Huggy to WV - A program very similar/slightly below K-State, then took them to a Final 4. Pretty damn solid results.
Lon to Florida - A program with zero history at the time, then took them to a Final 4. Decent success. Another Final 4 w/ OU.
Frank to SC - A hilariously bad program historically, then took them to a Final 4. Overall, way below .500 conference coach in a bad conference.
Tex to Washington - A program very similar to K-State at the time. Average results, no tourneys the rest of his days.
Cotton to NBA - P. decent results there.
