Beating Pitt to make your first Final 4 was the greatest followed by beating X to win BET, UCONN in 06, Kansas in 05, Duke in 09, OK in 05, and 3 wins over top 5 teams at Wells Fargo in 2013. IMO knocking off the overall #1 team which is a truly historic program is now his greatest victory. However that win will fall to #3 after next weekend.
