Andy Reid, Bruce Arians, Pete Caroll times two, Bill Belichick, Gary Kubiak, Tony Dungy,Jon Gruden, and Dick Vermeil were all retreads who won the big game and that's just this century. In fact i'd say it's more common than not that a coach who isn't coaching for the first team that hired him wins the superbowl. I like Reich and hopefully we give him someone better than Darnold to work with
