His shooting is coming to form but his D is still a hit or miss.

If you look across all defensive statistics, Terry Rozier is right up there with Marcus Smart - slightly better in some categories, slightly worse in others. Overall the statistics show that Rozier has had every bit as much impact on the defensive end as Smart has - and that is saying A LOT considering the type of defensive impact Smart has every night.
The difference is that people just don't give Rozier the respect or the time of day to put any faith in his abilities. People make up their minds that they want to dislike him before they even watch him play, and so all they see is bad.
I've been watching this kid with an open mind since the day he was drafted - he's come a huge way, and he's been VERY good defensively ever since last year's playoffs, when he routinely shut down John Wall when nobody else on the team could.
He's a different type of defensive player to Smart. Smart is more of a physical, "push your man around until he makes a mistake" type of defender. Rozier is more of an Avery Bradley "pressure your guy full court until he dribbles the ball off his foot" type of defender. He hassles opposing guards with full court pressure, gets them tired and worn out, often pressures them into mistakes that he doesn't get statistical credit for.
Smart's defensive style means that his defensive impact is more visually noticeable / obvious, but Rozier impacts the game defensively just as much - just does it in ways you don't necessarily jump out at you. He could be the most capable guy on this team when i comes to seeing a pass before it's going to happen and getting in to the passing lanes for steals and/or deflections.
