if we are thinking long term then they both need to go. Millsap is a great 6th man candidate and the 2nd best PF on the roster right now. Jefferson is our best center on the roster (maybe? Favors is probably better at C than him as well) but is not defensive minded enough to lead this team to a championship. I'd love to keep Millsap if he'd accept the backup PF role. But he won't, so he needs to go. In the end I don't know if it's in the best interest of the team to keep either of these players long term. But you know they are going to keep one of them this off season.
Last year I'd have rather kept Millsap. But right now he looks totally lazy and pathetic. His defense is actually worse than Jefferson right now and his offense is non-existent. He is not taking a reduction in playing time well, so how can we expect him to take a demotion to backup any better?
I feel as if Millsap has given up on the team and is not putting forth the same effort he has in the past.
