Tickets to the Final Four will be punched this week when the NCAA Tournament Sweet 16 tips off.
We've already seen preseason favorite Duke and defending champion Villanova go down, which tells you how hard it is just to get this far in the tournament. A host of perennial contenders highlight this week's action as UCLA, Kentucky, Kansas, North Carolina and Arizona hit the floor.
But we'll also get to see several teams not used to making it this far in the Big Dance, including South Carolina, Purdue and Xavier. will one of those underdogs make it to Phoenix, or will the blue bloods dominate the Final Four as expected?
