I know we all have love for Big Al and I am still a fan, but I am a little surprised more people wouldn't rather have Millsap. He seems like a more complete player at this stage of their careers and would offer more off the bench than Big Al - unless we are strictly looking at C eligible players.
And, as others have said, if Howard actually does want to come here next year, we use amnesty on which ever one we traded for. If not, we keep him and let him be productive.
