re: Now that the roster is set, which 5 man lineup will have the highest NetRtg?

Jrue
Crawford
Hill
Cunningham
Davis

Had the best overall net rating in their time on the court post all-star break.

Jrue
Moore
Hill
Davis
Cousins

Followed up second was the above lineup.

Without Hill its hard to say, but the OP's suggestion is a strong case given we will likely stagger minutes just like that. Really depends on how well Miller can be a consistent three point threat and not give up a ton defensively. And if Moore can find a bit more consistency. Otherwise you can see a situation where Rondo and Cousins play good consistently, but then Miller and Moore just cancel out good nights with cold streaks and its just a unit treading water.
