Unhappy in the CBA, Mitchell quit the team midway through the season to return home to Georgia, where a former professor hired him a Special Education teacher for the remainder of the school year. With his summer off, he tried out for the U.S. Basketball League, and joined the Tampa Bay Flash, who he helped lead to the league title. He rejoined the Rockets for training camp afterwards, but was once again cut and joined the CBA, splitting the season between the Wisconsin Flyers and Rapid City Thrillers. He then joined the French LNB Pro A team of Montpellier Basket (coached by Pierre Galle) for the end of the 1987–88 and the whole 1988–89 season.
