The New England Patriots beat Atlanta Falcons in Super Bowl LI in overtime. During regulation they never led the game. The only time they ever led was at the end of the game. Does this make the Patriots the first team ever to win the Lombardi trophy without ever leading except for the final results?
Equivalently, has there been any Super Bowl runner ups who never trailed except at the final whistle?
EDIT: Note that it is possible for a team to lose if they lead the entire game and the opposing team scores on a field goal that ends the game. Also for the purpose of the question, what I mean by saying not leading during the entire game is not leading in any time except the very last second of the game.
