Let's run down some of the top reserves who have helped their teams advance to the regional semifinals, and what they bring to the floor:
Nigel Hayes, Wisconsin: The freshman forward has provided a major boost off the bench for long stretches this season. He's a player who can score with his back to the basket.
Naz Long, Iowa State: Iowa State wouldn't be in the Sweet 16 without Long's outside shooting; he's hit clutch shot after clutch shot this season for the Cyclones.
Dwayne Polee, San Diego State: Polee has developed into a necessary second scorer for the Aztecs. Has put up 15 points and six boards in each of the tourney games.
