Downshifting: B. According to basketball-reference.com, Durant spent a career-high 25 percent of his minutes playing the power forward position this season. When the Thunder moved Durant to power forward and played with a small lineup, it put on the floor one of its most potent offensive units. Three of the Thunder’s top four most efficient offensive lineups came with Durant at power forward, according to 82games.com. The problem was defense. The Thunder struggled at times to consistently defend teams when relying on its small-ball look. Rebounding and protecting the rim became trouble areas. And though Durant tried his best to bang on the block, he suffered a drastic dip defensively, yielding 0.86 points per possession and 47.4 percent on post-ups, up from 0.75 points per possession and 37.2 percent last season.
