Derrick White is an outstanding perimeter defender. Possessing quick feet and dexterity, he calmly navigates the screen and maintains himself in front of even the most cunning ballhandlers. White isn’t huge, but he’s long enough to contest everything except the biggest wing in the league, where he attacks from the bounce.
He’s just as impactful off the ball. White has near-perfect timing and is rarely out of place when providing help and running rotations. He has a knack for reaching out to the passing and driving lanes at just the right moment to disrupt action or force a turnover.
White excels in nearly every way teams expect to provide defensive value to their guards, but his influence is not limited to such areas. He contributes in a way that is limited to big men: shot blocking.

White’s overall influence as a shot blocker is no match for the best bigs in the league. He simply doesn’t have the size to be a deterrent at the rim, and his responsibilities as a perimeter defender keep him occupied away from the basket, so he’s just as likely to be a player positioned near the hoop as he is. You can’t deny shots so often.
Being the best shot blocking guard in the league is a bit like being the fastest offensive lineman in the NFL. Interesting and useful, but ultimately incredibly unimportant.

Boston is competing at the highest level. Every detail matters. The extra defense White’s shot block provides gives the Celtics a slight advantage that shouldn’t be overlooked.
