College career
Stover played two years in college for UCLA. He was negatively profiled in a February 2012 Sports Illustrated article, which stated that he partnered with Reeves Nelson to erode team unity as a freshman and did not take practices seriously, often shooting free throws one handed or fading away. As a sophomore, he posted averages of 0.5 points and 1.5 rebounds in 28 games, recording 8.4 minutes per contest. His 1.4 blocks per game were a team high. In August 2012, he was dismissed from the team for failing to meet eligibility requirements. Coach Ben Howland said in a statement. "We are very disappointed that Anthony has not met his academic requirements. We had high expectations for him, and we were looking forward to getting increased contributions from him during this coming season."
