Being great in the regular season is commendable, but the NFL playoffs carry all the weight when it comes to legacies. How much different would the conversation be around Lamar Jackson if he was heading to his third or fourth Super Bowl this postseason?
Every playoff win helps build up a résumé. Andy Reid went from a head coach who had the reputation of never being able to win big to being mentioned as perhaps the greatest coach of all time with a few Super Bowl wins the past six seasons. He's one of many examples of coaches and players whose legacies completely changed after some postseason success.
