It takes desire to win the big dance, UNC desire missing?

It takes more than talent to win the NCAA Basketball Tournament a team also needs to have a strong desire to win. With no team dominating the college basketball landscape intangibles such as the desire a team has to win will have a big effect on this years tournament. The team that wins the tournament will most likely have a game which it needs to gut out and come up with the big play, and great defense down the stretch. The desire to win has already affected the big dance seeding, you can look no further than UCLA's big win against Stanford in the closing minute of Saturday's big game. UCLA had a strong desire to win and added to there bid for a #1 seed in the big dance.
Number 1 ranked North Carolina also had a big win against #5 Duke on Saturday and despite holding Duke scoreless for the final 5 1/2 minutes of the game, top basketball blogger Yoni Cohen declared in his recent post that UNC will not win the dance because of there lack of heart. To see what Yoni said in the post go to http://www.yocohoops.com/section/Commentary . Which teams going into the tournament are playing with the most heart??? Please leave a comment.
