Transparently, I didn't see the game. But I've posted this before (and my comment is from it being pointed out by a friend originally) --
Every team uses the high screen and roll. Every team (college, NBA). Those that can do it well, create mismatches that have the ball handler make the correct decision to gain the advantage (eg hit the short roll for a 4 on 3, swing to a corner for three, drive if not picked up, oop if its there, etc -- you get the point). Using a big up top that can catch the pocket pass, can manage a 4 on 3 is a huge benefit. If they can finish an oop, again, huge benefit coming downhill. It opens the lane so the initial ballhandler (eg JJ) has room to make the best decision and make it quickly and accurately.
I don't believe we run it well. I also don't believe we defend it well. And I know this is a gross oversimplification, but it's not a bad bellwether for how well a team is coached for how productive they are executing the high screen and roll and defending the high screen and roll, but that's just my opinion.
