It reminded me of game 1 against the Knicks. Yes, there were other issues, but the number one problem seemed to be that the C's were not sure how the Heat would defend them, and it completely killed them in the first half.
We saw some good adjustments in the second half however, which will hopefully continue to improve in game 2.
For me, the number one thing that stands out is the way the Heat send quick doubles to anyone in the post, particularly if there is a mismatch. They are so long and quick, and with the C's not expecting it, they basically made it impossible to attack mismatches in the post. In order to counter this, the C's are going to have to really be looking for the double quickly, and trying to pass out of it before they can get the trap there.
What I would like to see a lot of is give and goes with Rondo passing toe KG in the post, and then flashing to the middle when his man doubles. Once he catches the ball in the lane, the other defenders will collapse down on him, and he will be free to pick the defense apart and find the open shooters.
