Houston furniture salesman Jim McIngvale aka ‘Mattress Mack’ has been known to place crazy high sports bets before. But this is his biggest mobile bet yet…he’s betting $4.5 million that the Bengals will beat the Rams on Sunday. If they come through, McIngvale stands to gain $7.7 million.

 

SI Sportsbook has the Bengals at the 4.5 underdog.  But McIngvale isn’t taking the points…he just likes the Bengals. It’s reportedly the single biggest mobile bet of all-time, and the system wouldn’t allow it to be place as one lumps sum. McIngvale told ESPN, “I had to make like twenty $200,000 bets to make it work.” His track record has been up and down…he won big last year putting $3.5 million down on the Buccaneers.  But he LOST on a more than $13 million bet on the Astros to win the World Series. Oopsies.
