Mattress Mack bet big on the Super Bowl underdog and it paid off.

Jim McIngvale bet $3.46 million on the Tampa Bay Buccaneers +3.5 points in Sunday’s Super Bowl. The Bucs thrashed the Chiefs 31-9, making McIngvale an easy winner. Tampa Bay was a 3.5-point underdog, meaning, for McIngvale to win his bet, all the Bucs had to do was not lose by more than three points. They didn’t need any points.
