John Wallace against Rhode Island in Hawaii his SR, jumping over Preston Murphy for a tomahawk is one of the most underappreciated 'Cuse dunks of all time.
Best Warrick dunk I ever saw was when he was in high school. Coming down on a fastbreak he jumped into the air about 2 feet inside of the foul line to try a one-handed tomahawk - 2 defenders jumped up to contest him, knocking him off balance. He was still high enough that he just rotated his body about 90 degrees and threw it in with two hands on the side of the rim. Absolutely positively incredible.
IMO his second best dunk was his breakaway reverse dunk at the end of a game against Seton Hall his JR year. He jumped from like 10-11 feet out, did a 180 while flying towards the basket, and reversed it in. Amazing. I have a video of it somewhere in my OrangeNation archives.
