Here's a list of the last 10 CWS champions and how they followed up the 3 years after winning the CWS. Aside from OSU winning back to back titles, the only program to make it back to the CWS within 3 years of winning it was South Carolina. In fact, the vast majority of the time in those 3 years after winning the CWS teams did not even make it out of a regional. Amazingly, not one of these schools was dumb enough to fire their coach after the "obvious steady decline in their programs". But then again I doubt any of these ADs waste their time getting the expert opinions of the abundantly ignorant posters on FGF. Go figure...
