The game was played at AT&T Stadium, the host of this year's Final Four.
In his final collegiate game, Sheehey shined with a team full of guys that seemed to gel well together. They were seen laughing and goofing around together after the victory.
"We had guys that really gelled together," said St. Louis' Dwayne Evans, who had 15 points. "It was easy-going out there, and guys were ready to compete. Three days, after a couple practices, you get to know each other pretty well, and we all had fun out there."
