David West is arguably one of the best (if not the best) players that Xavier ever had.  As a Musketeer, the Power Forward was named the Atlantic 10 Player of the Year three times (2001-03) and was also named the AP National Player of the Year in 2003. 

David West's best years were with the New Orleans Pelicans, where he would be a two-time All-Star.  That being said, West still had plenty to offer the Pacers when he signed with them as a Free Agent in 2011.
