The New England Patriots pulled off the greatest comeback in Super Bowl history, rallying from a 25-point deficit to beat the Atlanta Falcons 34-28 in overtime.
They may have also capped one of the greatest one-year stretches in U.S. sports history.
The run started last April, when Villanova knocked off North Carolina on Kris Jenkins' buzzer-beating shot in the NCAA Tournament title game in Houston _ the same stadium where the Patriots won.
The Cleveland Cavaliers followed that by rallying from a 3-1 deficit in the NBA Finals and beat the Golden State Warriors in a tense Game 7 that wasn't decided until the final minute.
The Chicago Cubs took their turn in November, ending 108 years of frustration by outlasting the Cleveland Indians 8-7 in 10 innings of Game 7 in the World Series.
Not to be outdone, college football had one of the most thrilling championship games in its history, with Clemson scoring with 1 second left to knock off top-ranked Alabama 35-31.
Not a bad year at all. Maybe the best ever.
