Williams voiced the decision on Tuesday after earning 11 points and eight rebounds in the Bucks' 103-94 season-ending loss to the Miami Heat in Game 5 of a second-round series. The former University of North Carolina star was selected second overall in the 2005 NBA draft by the Atlanta Hawks. Williams, 34, averaged 10.2 points and 5.2 rebounds in 1072 NBA games.
"I've been very blessed. God has been very, very good to me," Williams said.
Bucks guard Kyle Korver also told The Undefeated he will talk to his family before deciding on his NBA future. The 39-year-old has played in 17 seasons, has made one NBA All-Star appearance and has made 2,450 3-pointers. Korver is now an unrestricted free agent.
