Millsap thrives moving off the ball on the baseline and free throw line extended. Unfortunately, with Al and Mo handling the ball, there's really no reason for him to continue searching for space, as no one's going to find him. You still see him, from time to time, making really smart passes from the high post and short corner, but he's forcing the issue far too much. If this team acquired a point guard who had half a clue in the halfcourt and moved Jefferson, I think we'd see Millsap's attitude and efficiency get a lot better. Since Deron was traded, Millsap's been called upon to be more of an iso scorer, which is just plain stupid. You also see him not committing fully in help defense, but on many occasions, it seems as though he's hedging against passes, as he's not confident anyone (Jefferson) will help the helper.
With all that said, Millsap needs to play his game, continue to run the floor, take shots in the flow of the offense (whatever that is), and commit in help defense (if Jefferson hangs him out to dry, so be it). If he doesn't make the right decisions/plays, especially if/when the Jazz move Jeffy and start executing their offense competently (which might take a new point guard), he should be moved as well. Millsap at his best is a smart, efficient team basketball player. Hopefully the last two years haven't ruined him for good.
