This had Gregory's fingerprints all over it again. The stalled offense, Collins to the basket one-on-three. In the last 3 years we have blown 20 second-half leads (this was #21), so in this game Gregory doesn't pull him out (if Collins indeed was growing rogue) or he went back to the one-play playbook he has late in games. If you watch the replay, you will see its the later. Everyone spreads the floor, Collins comes to the ball and everyone spreads out. Its a designed play.
This is on Gregory. He routinely gets away from what work the first 30-35 minutes of games and we wind up coughing up the game instead.
