The Suns' training camp just got a little more competitive. With seven guards already under contract the Suns signed shooting guard Dionte Christmas on Friday after he showed his pure scoring ability on their NBA Summer League entry in July. Christmas a 6-foot-5 guard who has improved tremendously on defense since his Temple years averaged 10.1 points in only 20.9 minutes per game over seven reserve appearances in Las Vegas. He shot 46 percent from the field and 32 percent on 3-pointers showing an adept ability to quickly get his shot off and to score in catch-and-shoot situations. Christmas signed a multi-year contract with a small guarantee on the first season a deal that is similar in structure to what he had with Boston last year. Suns general manager Ryan McDonough was with Boston last year when Christmas was waived during the preseason. "He was a key contributor for our Las Vegas Summer League team and his scoring ability leadership and toughness will help us this season" McDonough said in a prepared statement.
