During George Mason's captivating run through the NCAA tournament, Butler became a symbol of Cinderella and the tournament collectively with his tenacious heart and infectious smile and was featured on the cover of the March 27, 2006 edition of Sports Illustrated magazine. Following GMU's stunning 86-84 overtime victory against the top-seeded UConn Huskies in the Washington D.C. Regional Final, Butler was named the region's Most Valuable Player. He scored 13 points against Michigan State in the first round, 18 points against North Carolina in the second round, 14 points against Wichita State in the Sweet Sixteen, and 19 points against UConn in the Elite Eight. After the regional final, Butler and his father were in tears as they hugged at length on the court. It hearkened memories of Butler's recruiting by GMU, during which he brashly predicted to Coach Jim Larranaga that he would lead the Patriots to the Final Four. "I think I was joking when I said that," Butler said. "I started dreaming when I got to college. It shows you anything can happen." Butler and the Patriots then headed to Indianapolis, where they faced the Florida Gators, led by Minnesota Regional MVP Joakim Noah. To the dismay of many across the country rooting for the team leading one of the greatest Cinderella stories in sports history, George Mason was defeated by Florida in the Final Four 73-58 on Saturday, April 1, 2006.
