Gruden didn’t win his playoff appearances after ‘02 but I think he was more above average than mediocre-bad after the SB. He had 2 NFCS titles in Tampa post-SB. 4 winning seasons out of 7 overall there. He had 5 losses of 3 points or less in the 7-9 season the year after the SB. He produced winning seasons with QBs that were 2nd or 3rd QBs anywhere else or out of the league level. But he maxed out Griese, Simms, Gradkowski, and older Brad Johnson enough to win a decent amount of games. I think his wins reflected the furthest he could go with the QB talent that his two Tampa GMs gave him.
