25. Tyler Hansbrough, North Carolina

Hansbrough was one of the hardest-playing players in the history of college basketball. He never took a play off. He ran the floor consistently, pursued every rebound and played through contact. He had an insatiable desire to win and imposed his will on the game every night. He averaged 18.5 points and 8.5 rebounds in his NCAA tournament career, leading North Carolina to a national championship in 2009 as well as a Final Four (2008) and an Elite Eight (2007) appearance. -- Seth Greenberg
