He was a good regular season coach but he was god awful as a playoff coach. His ultra-conservatism caught up with him. To win playoff games you often have to take chances offensively, he never got that concept....and before folks start saying but Carl Smith, Carl Smith hung around so long because Mora embraced his offensive philosophy (for the life of me I can't see how folks don't get that).
He brought the Saints to a level of respectability but never won a playoff game in his career, even at Indy with Peyton Manning (albeit a young Manning)....
