Norwich went 16-11 overall and 11-7 in the league in 2010-11, its first above-.500 showings since 2006-07. The squad also garnered its first postseason win since 2005-06.

Rock was a counselor at the Five Star Basketball Camp between 2008 and 2010 after serving as a varsity boys' assistant coach at Rice Memorial High School, his alma mater, during the 2006-07 season, leading the team to the Division I state title. Rock was previously the junior varsity boys' head coach for two seasons at Rice.

A four-year member of the Norwich men's basketball team, Rock was a captain during his junior and senior seasons. As a senior in 2000-01, he led the Cadets in scoring (13.0), assists per game (5.2) and free throw shooting (84.9%). Rock completed his degree in communications in 2009.
