Smart period. Price does not figure into it. Smart is flat out better than Rozier. Smart is better $77mil and he is better at $97mil.
Rozier is the inferior player - why, mainly because of his limitations as a passer & playmaker as a lead guard. Also because his defense is middle of the pack which makes him hugely reliant on scoring output to influence games which he does well but not great (over-reliance on long range shooting, lack of easy hoops, makes him a streaky scorer).
Got to disagree here.
Rozier is a better player by a significant margin. Smart is somewhat better as a true point, but that advantage isn't helpful because he insists on imposing himself on the offense more than he should. Tatum and Brown can break the defense much more efficiently than Smart can. Smart slows down the offense. Rozier speeds it up,
Its been a while since Rozier ran anything here, and he typically played as a combo guard at Charlotte, but when he was most successful, he pushed the pace hard, and either created a quick advantage or gave up the ball. We should be a great running team. There were times when he over-pounded the rock like Smart does, and that wasn't effective. But given his evolution, it looks like he's dealt with his worst habits much more effectively than Marcus has.
This team needs pace, movement and support shooting way more than it needs a playmaking point, and Marcus just isn't good enough to make that work for a top team.
I don't even think he provides that much of defensive upgrade over Rozier. Marcus does most of his best work against bigger players in the lane. He's much more mediocre staying in front of talented point guards. He's just not quick enough. Rozier is actually better at that than he is.
Rozier is pretty well suited to playing a complementary role with Tatum and Brown. We should have kept him.
