Retired forward Tayshaun Prince will soon be named special assistant to Grizzlies general manager Chris Wallace, according to several NBA sources. Prince, 37, played for the Grizzlies from Jan. 2013-15. Prince and Austin Daye were traded to the Grizzlies in a three-team deal that sent Rudy Gay and Hamed Haddadi to the Toronto Raptors, and the Raptors sent José Calderón to the Detroit Pistons. The Grizzlies also received Ed Davis from the Raptors. Prince was eventually traded to the Boston Celtics in a 2015 three-team deal involving the Grizzlies and the New Orleans Pelicans. Before the trade, Prince helped the Grizzlies reach the 2013 Western Conference finals. Prince is widely considered a big influence in NBA locker rooms and operated as a calming voice with Grizzlies players. The Grizzlies believe Prince will bring a unique voice to front office decisions. Before the 2014-15 season, Prince started 838 regular-season games since the beginning of the 2003-04 season with the Detroit Pistons. That was the second-most in the NBA, behind Cleveland’s LeBron James.
