The 2011-12 college basketball season is right around the corner, but that doesn't mean that the season of speculation hasn't already begun.
With the release of both the Associated Press and the ESPN/USA Today preseason polls, the North Carolina Tar Heels have been nearly unanimously selected as the early favorite to take home the National Championship in New Orleans come April.
With a nearly unstoppable front-court in the form of Tyler Zeller and John Henson, the nation's most talented player, Harrison Barnes, and a rapidly maturing back-court led by Kendall Marshall and Dexter Strickland, the Tar Heels are already looking nearly unstoppable on the road to another Championship.
That being said, there are challengers along the way. Certainly North Carolina will lose a few games this year (as nearly everyone knows, going undefeated is exceedingly rare in any sport), but are there any teams who could legitimately stand in the Tar Heels way and prevent them from reigning supreme once more?
Here, we'll take a look at the top teams what have the potential to unseat the Tar Heels atop the world of college basketball and contend for the National Championship.
