We're now through the Round of 32 in March Madness, but the slate of teams that made it to the second round isn't quite as expected, as No. 1s Purdue and Kansas have been sent packing, along with No. 2s Arizona and Marquette. The unpredictability of the NCAA Tournament is what makes it so great, but at least you can count on a return by locking in some of the March Madness betting promos and bonuses being offered right now by the top online sportsbooks.
FDU’s underdog run ended on Sunday against No. 9 Florida Atlantic but fellow Garden State giant-slayer Princeton followed up its Round 1 victory over No. 2 Arizona with a 15-point win over No. 7 Missouri.
