I didn't get to see the game. Listened to parts on the radio. In looking at the box score, a couple of things jumped out at me. We had 11 OReb (Smart had 3) and 5 TO as compared to 8 OReb and 15 TO for Cleveland. That is plus 13 possessions.
Pretty good considering they started Thompson in part because he get offensive rebounds. Jeff Green had 5 TO and LeBron had 6. Smart was +21.
This is an amazing run by the Celtics. I have been watching the NBA a long time, never seen a team this young (including the coach) do this well.
