Kendall Marshall broke his wrist, and the North Carolina Tar Heels suddenly don’t look so good. Despite the 87-71 win in the third round over Creighton, sending them into the sweet sixteen for the fifth time in six years, the mood isn’t great. Marshall, who led the team with 18 points and 11 assists, is probably irreplaceable, and even if he somehow plays, it won’t be the same.
