We're now halfway through the Sweet 16, with surprising Florida Atlantic joining Kansas State, UConn and Gonzaga in the Elite 8 following Thursday night victories. The Owls are one win away from joining the 2013 Wichita State team as the only No. 9 seeds to advance to the Final Four. 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.
Powerhouses Alabama, Houston and Texas are all favored to advance in Day 2 of the Sweet 16 tonight, but all eyes will be focused on No. 15 Princeton, which will look to keep its Cinderella run going against No. 6 Creighton in the South Regional in Louisville.
