It figured that backcourt sprinters Goran Dragic and Gerald Green would be the ones accelerating the Suns as they raced to 30 points in the first 8 1/2 minutes of Monday night’s win at Philadelphia. It helps when their big man has the same energy to stoke his team. After a midseason malaise, Suns center Miles Plumlee has popped back in recent games for more of the rim-shaking, board-hammering play that made him — and the Suns — sensations for the first half of the season. On Monday night, Plumlee notched his first double-double (14 points and 13 rebounds) in two weeks to help the Suns move to 2-0 on a road trip that ends with games at the league’s worst team (Milwaukee) Wednesday night and the league’s best team (Indiana) on Thursday night. Plumlee was a tone setter early against Philadelphia, when he scored eight points during a 30-17 Suns start. Six of his points came on follows, including two slams off his own misses, as if he were on the playground tossing the ball up off the hoop to himself. “I feel like I’m getting back,” Plumlee said. “I’m definitely doing some of the simple things, but there’s still a lot of stuff that I’m leaving on the table — a lot of dunks I should have and moves I should make stronger. I’m not entirely satisfied, but it’s a step in the right direction.” Plumlee has averaged 10.5 points and 9.0 rebounds over the past four games. He seems to light up at the sight of Philadelphia with an athletic advantage against Spencer Hawes. He had a career-high 22-point game against the 76ers on Dec. 28 and took a career-high 15 shots against them Monday night. He said his post game feels simplified and comfortable now that he is focusing on getting deeper post position and knowing what move he will go into quickly.
