I recently found Byron Mouton (2000-02) on the 2005-06 roster of the ABA's Baltimore Pearls.
Here is an NBA-DL player profile for Byron Mouton, where he appears to have played for the NBA-D League's Florida Flames for the 2004-05 season. Working backwards from that profile, I learned that Mouton previously played for Braunschweig in Germany in 2003-04 (where he would have been a teammate of Mike Mardesich) and the CBA's Idaho Stampede in 2002-03. He was the 3rd pick in the 2002 CBA draft. He was briefly signed to play on French Pro B-League's FC Mulhouse in summer 2005, but it's unclear if he appeared in any games before leaving the team to play back in the U.S.
Byron Mouton transferred to Maryland from Tulane and redshirted the 1999-2000 season. He was a starter on the 2002 NCAA championship team. After going undrafted in the 2002 NBA draft, he played for the Washington Wizards' summer league team and then was invited to the Boston Celtics training camp before reporting to the Idaho Stampede for the 2002-03 regular season.
