We need a Point Guard, someone who can dribble, distribute, penetrate, and be a reliable shooter.
We don't need Rozier, a guy who can't dribble, has minimal court vision, is an unreliable shooter, and absolutely zero basketball intuition. He's a very good athlete masquerading as a basketball player, which he might get away with he if played power forward or something. The only thing he's good as is rebounding for a guy his size. I'll be pretty annoyed if we have to watch him lead an offense at all in 2020
