The deal will reunite Butler with new Detroit president/coach Stan Van Gundy, under whom he played in Miami early in his career.
The Pistons also agreed to a two-year, $6 million deal with point guard D.J. Augustin, sources close to the situation told The Associated Press. Augustin, 26, averaged 13.1 points per game and made 40 percent of his 3-pointers for the Chicago Bulls after the team claimed him off waivers from the Toronto Raptors this past season.
