Floyd Mayweather Jr. is going to jail for 90 days pretty soon so he has a few things to get off his chest today. Minutes ago he started tweeting his winning gambling tickets from NFL and college football including this insane, $400,000 bet on the 49ers at Seattle on Christmas Eve. You might remember how San Fran escaped with a 19-17 win. The line, as you can see, was -1.5 for a cool $347,826 casher. Wait until you see how much he put on Purdue. JUMP!
