The club currently plays in the LNB Pro A, the highest-tier level in French basketball.
The pick was originally owned by Phoenix but the Pacers held it entering draft night. They received cash for the pick and the Bucks took the 21-year-old guard for draft-and-stash purposes.
Besson was the last pick of the draft at No. 58 and had remained unsigned. He played for the New Zealand Breakers last season, averaging 13.9 PPG, 4.0 RPG and 2.3 RPG in 25 games.
He joined the Bucks’ Summer League team and averaged 2.5 PPG and 11.4 MPG in four games.
