Keyon Dooling will remain a Boston Celtic for another season, for the league minimum. Per the Boston Globe: “The Celtics Tuesday officially lost center Greg Stiemsma to the Timberwolves, but they did re-sign guard Keyon Dooling to a one-year contract, according to an NBA source. Boston rescinded its qualifying offer to Stiemsma, making him an unrestricted free agent and allowing him to sign with the Timberwolves, who offered him a contract in the neighborhood of $3 million per season. Stiemsma was plucked from the NBADL’s Sioux Falls Skyforce in December and briefly became a sensation with the Celtics before settling into a backup role. [...] The Celtics were able to get Dooling back at the league minimum after there had been some initial interest in him from the Wizards, who signed former UConn standout and Pacer A.J. Price to be their backup point guard. Dooling again will be Rajon Rondo’s backup and mentor after an uneven first season in Boston that ended positively. After an injury plagued first half of last season, Dooling cemented himself as Rondo’s primary reserve and impressed coach Doc Rivers with his defensive intensity and occasional 3-point shooting. He canned 11 3-pointers in 20 postseason games and scored 10 points in a Game 4 victory over the Heat in the Eastern Conference finals. Dooling’s return likely will please Rondo, as they developed a close relationship and shared long conversations about basketball at their neighboring lockers.”
