Kravstov appeared in 25 games with the Detroit Pistons as a rookie. He went to the Bucks on July 31 as part of the trade that sent Brandon Jennings to Detroit.
The trade is the latest in a series of efforts by the new general manager McDonough and new coach Jeff Hornacek to rebuild the Suns after the team endured its second-worst finish in franchise history.
Butler had expressed satisfaction with the role made for him in Phoenix, even serving as one of the models at a local shopping mall when the Suns unveiled their new uniforms.
But he undoubtedly will love the move back to his home area.
Butler, a two-time All-Star, started 78 games for the Clippers last season, averaging 10.4 points per game, shooting 39 percent from 3-point range.
After two seasons at UConn, Butler was selected by Miami as the 10th overall pick in the 2002 draft. His uniform numbers have been retired by the two high schools where he played, Racine Park, Wis., and Maine Central Institute.
