Correction, March 17, 2014: This interactive originally assigned an incorrect ranking to Providence College's football team, which showed the school reaching the Sweet 16 using the "Football" category. Providence no longer has a football team and would lose to UNC in the first round based on this fact. The interactive also originally showed the University of Arizona losing in the "Cat Lovers" bracket. However, since their mascot is the Wildcat, they would in fact win the "Cat Lovers" bracket.
