I am not a Birdman fan. I never felt like he was any more than a human pogo stick. He could dunk the ball, and he could block a couple shots, but he had very little basketball skill, and was not a good defender.
We need to be looking for a replacement for PJ (assuming he is gone)who understands the team defense, and is able to bang down low with the bigger centers in the league. Anderson is not that man.
