So I didn't really follow the game as closely as I normally do, but the difference defensively is us basically not switching nearly as much and not giftwrapping the Celtics easy paint points and instead letting them earn them from the perimeter, especially off the dribble?
It was mindboggling and simply idiotic of us to switch the Morris/Smart PnRs. Same with Rozier to a lesser extent. They are not efficient shooters off the dribble.
It's not like we contested every shot behind the 3pt line and an open shot is still way more efficient than allowing a post up against Hill without help.
Oh yeah, and some King effort help too.
