Raptors first-year coach and former Mavericks assistant Dwane Casey got a big surprise when Knicks center Tyson Chandler presented him his championship ring in a ceremony before last night's thrilling 90-87 Knicks win. Casey got his ring in the mail Sunday, but the Raptors wanted to see a more public presentation, and who better than his defensive anchor with the Mavericks last season, Chandler, to give him the ring officially. Casey wasn't told about the ceremony, which included video messages from Dallas' Jason Kidd, coach Rick Carlisle and Dirk Nowitzki.
