Up next are the top-seeded North Carolina Tar Heels, the preseason favorite to win the national title and one of college basketball's most storied programs. The Tar Heels are seeking their 99th NCAA Tournament victory, which would break a tie with Kentucky for the most by any school.

Tonight in the South Regional semifinals against the Tar Heels, Gonzaga (8.5-point underdogs) will be trying to shake up an NCAA Tournament in which few favorites have lost.

The Tar Heels are unlikely to overlook Gonzaga, especially since the Zags beat North Carolina at Madison Square Garden in 2006. Josh Heytvelt outplayed Tyler Hansbrough in that game, and Jeremy Pargo and Matt Bouldin both scored in double figures for the Bulldogs.

Heytvelt leads Gonzaga at 14.9 points per game, and he also shoots 41 percent from 3-point range.
