NOTES: Green returned to Oklahoma City for the first time since he was dealt to the Celtics along with Nenad Krstic and a first-round pick for Perkins and Nate Robinson at the trade deadline in 2011. But Thunder coach Scott Brooks has never lost touch with the former first-round pick. "We text throughout the year," Brooks said. "I'm glad he's back playing good basketball. He's a great young man." ... Despite tying an NBA record on March 5 with the fewest number of turnovers in a game, Oklahoma City still ranks 26th in the league in turnover percentage. ... Since being traded to the Celtics, Jordan Crawford has not been the explosive scorer many thought he would be. In his seven previous games, Crawford has scored in double figures twice and is averaging 5.6 points. ... Boston coach Doc Rivers said he has given up on trying to devise defensive schemes to stop Durant. He is relying on divine intervention. "You pray," Rivers said. "I'm serious. I don't know if there is a way besides attacking and being physical offensively. When you look at the Miami games, it's not that they guard him great. LeBron attacks him great." ... Hugo High's Trey Johnson, who has gained national attention for scoring the winning basket for the opposing team Friday during the Oklahoma state tournament, was a guest of the Thunder. He sat next to owner Aubrey McClendon.
