Marcus Smart
Jae Crowder
Avery Bradley

5B) Terry Rozier
I think a lot of folks don't realize Rozier is a really good defender. Not Marcus Smart good, but AB good I think in the future.
As JPotter said, any All-Defense list for the C's starts with Smart. He's one of, if not THE best defensive rookie I've ever seen (I'm only 24, so that's not that long, tbh.). He's so good on that end that I expect him to be a DPOY candidate going forward. He's got Tony Allen/Gary Payton level skills on D. He may not turn into a "star" in the traditional sense (But he could, IMO) but is Tony Allen with an offensive game not a star?
I think it says a lot about our new team identity that we have legitimately good-great defenders who can play multiple positions everywhere on the floor.
