The key? Not by itself. Maintaining stability with Dooley, Jones, or Pruitt wouldn't have built us a winning program (and maintaining stability with Kiffin would have had us on major probation). But Heupel has just won 38 games (with a shot at 39) over a four year period, something we haven't seen since 2001-2004. In my view, the odds that a replacement would underperform Heupel are much greater than the odds that a replacement would outperform him, and I believe that what he has accomplished here gives reasonable grounds for hope (not certainty) that he will continue to improve the program.
