WATCH: Best of Brad Stevens 2019-20 play reactions

While Boston Celtics head coach Brad Stevens may be closer to Clark Kent than Bobby Knight, his sideline reactions are still the stuff of legend.

Not too high, not too low — unless the ref blows the call?

This can be, at times, a more accurate iteration of Boston Celtics head coach Brad Stevens’ well-known game philosophy.

But the mild-mannered coach has been getting looser in the driver’s seat each season while he’s been with the franchise, even getting caught on camera letting loose on some especially egregious missed calls with curse words.

And even on the G-rated responses, Stevens’ sideline antics can be a show unto themselves, both demonstrative and reserved (for the post part) simultaneously.

So if you’ve got some time on your hands (like most of us do these days) give the video below a watch — and try not to smirk too much while you watch it.

Just don’t ask him to try a coach’s challenge — we all know how that will end.
