Perktonite?
He has truly been incredible defensively. Dwight's got two moves going for him in this series. One is the sweeping hook across the lane. The other is a counter off that where he goes across the lane then spins back for a jump hook.
Perk bodies him on the first, pushing him away from the lane, and he doesnt go for up fakes on the second, forcing D-Howard to shoot a contested hook over someone as tall as him.
It's so much fun to watch Perk grow defensively (and as an all-around player too I should add)
