Milwaukee Bucks guard Bryn Forbes is declining his player option for the 2021-22 season and will become an unrestricted free agent, sources told ESPN on Tuesday.

Forbes played a significant role off the bench as the Bucks delivered the franchise's first NBA championship in 50 years. He had his most efficient NBA season in several offensive categories, including 3-point percentage and true shooting percentage.

Forbes, 28, was fourth in the NBA in 3-point shooting (45.2%) -- and third best among players with 200-plus attempts. Forbes averaged 12.2 points on 48% 3-point shooting in February when starting guard Jrue Holiday was sidelined.

In the postseason, Forbes' impact was felt most significantly in the first-round series sweep of the Miami Heat. He made seven 3-pointers in the clinching game, most for Milwaukee since Ray Allen made nine 3-pointers in the 2001 Eastern Conference finals Game 6 against Philadelphia.

For the regular season, Forbes averaged 10 points in 19 minutes a game. Forbes played his first four NBA seasons with the San Antonio Spurs before joining the Bucks in free agency a year ago. He was an All-Big 10 players at Michigan State in college.
