I thought all along that we should be able to bring back JJ or Amir for the room exception. Amir is obviously gone to Philly, but JJ still makes a lot of sense. I do wish he had the ability to play center and if he is the last significant piece we add, he will, but he is like the ultimate team and system guy.
A bigs rotation of Horford, Morris, JJ, Zizic, and Theis is a little on the small side, but we really just need to fill the other 16 or so minutes that Al isn't in the game for the center position. Guys like Hayward, Crowder, and Tatum can certainly fill in at PF.
