LAS VEGAS — Late Saturday morning, Patrick McCaw stopped behind a small scrum of reporters surrounding Kevon Looney and pointed to his left wrist. Not necessarily known for his long-range exploits, he shot 5-for-11 from three-point range. McCaw, who spent much of his rookie season oscillating between shooting guard and small forward, also initiated the offense with poise. "We know how talented he is," said Chris DeMarco, the Warriors' Summer League head coach. McCaw's AAU team, the Chicago-based Mac Irvin Fire, featured five players ahead of him on recruiting boards. McCaw was a fill-in starter at small forward when Kevin Durant missed six weeks with a left knee injury. McCaw played solid defense, set screens and found open teammates. [...] shortly after Golden State won the NBA title, McCaw's focus turned to outplaying some of the 2017 draft's top picks in Summer League. The former Washington standout, who matched up on McCaw at times, scored eight points on 3-for-12 shooting before leaving with a left ankle injury in the third quarter. Damian Jones, who spent most of his rookie season in the Development League, had 13 points on 5-for-8 shooting with three blocks.
