PHOENIX — In practices, when coaches review concepts, Draymond Green idly chews his nails. A basketball savant, he can anticipate plays before they unfold, name every NBA player's weaknesses and detail all five positions' responsibilities at any given moment. The problem: Because Green's on-court IQ is unmatched, he sometimes gets bored when not challenged. By that measure, the Warriors' recent wave of injuries was well-timed for an undersized power forward whose playing style requires controlled chaos. Three weeks until the playoffs, after five months dogged by the knowledge that the regular season is just a prelude to the games that matter, Green is adding duties to an already sizable workload.
