I'm pretty surprised by these answers. While it is true that Favors/AJ make a better duo, Millsap is easily the one to keep. Jefferson simply dictates the pace of the team. Corbin had the right idea of making the Jazz a fast-break team, and when it works, it's really beautiful to watch. But that typically happens when AJ is on the bench, as he is slow up and down the court, and is too contemplative once he gets the rebound. More importantly, on the other side of the court, Jefferson posts up and waits for the ball, and once he gets it, he is guaranteed to hold it for a very long time. This is true regardless of his improvements in passing out or what have you. He will always hold the ball for a second, look around, most likely perform a couple of fakes, then either pass out or shoot. That means the only offense the Jazz can run must be centered around Jefferson's style.
So, yeah, I'd keep Millsap if the team is to grow and evolve.
