Jesus you guys think you can just throw guys in there because they match in size? Perkins on the floor = playing 4v5 offense, if not 4v6. On D he will be PnR'd to fucking hell because he is not familiar with our switch patterns and defensive schemes.
You think they are just gonna feed Drummond and let him battle it out? They will PnR the shit out of Perkins, knowing he would hedge too high, switch unnecesarily and get in the way of the guard to stay with his man.
Not counting ISOs, basically all of our set plays depend on precise movement. Having Perkins in there is like having a cardboard cut out.
Our way back into the game is making plays for Kyrie and JR and getting them back in the game, and Moz not getting called for shitty fouls for quite some time.
