I said Millsap, but Griffin might be good, too. Millsap is a team player who can do everything.
Uniting him with Horford again makes sense--they would be better than Atlanta was with them because they have a better backcourt. Griffin isn't quite as versatile, but he's more explosive and more physical. Better scorer. Millsap might be better rebounder, though Griffin plays in Jordan's shadow.
Noel is still developing. He can't shoot, but can block shots and rebound. He's getting stronger every year. Pretty frail when they drafted him. Then they had to wait for a year on his knee.
Still gets hurt too often. Good defensive player, but not that durable yet.
I don't know if they can get Noel from Philly at this point. God knows Philly is overloaded with bigs. That Holmes kid might be another good one. They have to deal, but we don't have Dunn to deal with them. I don't know if they would take Rozier or Jackson for him. Both looked pretty good yesterday. It would probably take more than that.
