Davis began his junior basketball season at 6 feet 8 inches (2. 03 m), saying he felt fortunate to have had such a rapid growth spurt without any knee pains. During his junior year, his family considered having him transfer to one of Chicago's basketball powerhouses, but Hyde Park Career Academy head coach Donnie Kirksey advised against it, saying "If you're good enough, they'll find you wherever you are". Perspectives finished the season 8–15. Although he remained unnoticed nationally and locally after three seasons of Chicago Public League play, he was soon thereafter rated as the number one player in the class of 2011 by Scout. com and was listed in the ESPNU 100. Attention came when he started playing on Tai Streets' Meanstreets (AAU team) traveling system in the spring of his junior year. In late April, Syracuse University offered him a scholarship. That spring, NBA Top 100 Camp Director Dave Telep invited him to the camp based on his dominant first half performance of the first game of the Fort Wayne, Indiana Spiece Fieldhouse event. In August 2010, Davis played in the Nike Global Challenge in Hillsboro, Oregon. In the opening game, he had 23 points and 9 rebounds.
