For all those claiming we should have gone big, here is the issue.
In order to be able to punish the Heat for their lack of size, you need to have an elite low post scorer. The C's don't have one of those. There are only a couple of them in the league right now. KG is the closest we have (and really the closest most teams have), and he had a bad game.
Defensively, it would have been nice to have another shotblocker in there, but that wasn't the problem. The problem was with pick and roll defense on the perimeter, and rotations on the Heats (spectacular) ball movement. Putting a guy like Wilcox or Darko in there, would have just slowed the C's rotation and pick and roll defense down even more.
I think Doc made the right move in going small, in order to try to get quick feet out there to close out shooters, and close out lanes. Unfortunately, most of those quicker feet were still moving at preseason speed, while the Heat were much closer to playoff speed.
Hopefully by the next time we play them, KG will be back to where he was last year, so he can make them pay down low, Green, Terry, Bass, KG (yes, KG was also very weak defensively) and others will have sped up their rotations, and locked in more on the pick and rolls, and things will look a bit different.
In the meantime, I am excited for Friday to see how they bounce back, and see how guys like Green and Sullinger adjust to more standard regular season speed (rather than playoff speed that the Heat were playing at).
