MLS
On February 6–7, 1996, Major League Soccer (MLS) held its first draft. The Columbus Crew selected Thompson in the third round (21st overall) ahead of fellow Bruins Eddie Lewis, Frankie Hejduk, and Ante Razov. At the time he was playing indoor soccer with the Tampa Bay Terror of the National Professional Soccer League. Thompson went on to play four seasons with the Crew. However, at the end of his second season, in which he saw time in only six games (four as a starter), the Crew did not protect Thompson during the expansion draft. The next season, he came back strong, appearing in twenty-nine games. However, he retired at the end of the 1999 season finishing with 4 goals and 18 assists for his MLS career.
