With Missouri basketball guards Tamar Bates, Caleb Grill and Tony Perkins all graduated, head coach Dennis Gates was in need of replacements for the upcoming season. Mack spent his freshman and sophomore seasons as part of the UCLA Bruins, where he carved out solid role. Across his two seasons at UCLA, Mack played in 67 games, starting in 31 of them. Prior to his time at UCLA, Mack played high school ball at Coronado High School in Henderson, Nevada. It’s difficult to project an exact role for Mack next season, but his versatility projects him as an impact player for the Tigers next season.
