Kobe got a great screen from Lamar Odom that allowed him to get a step on DeShawn Stevenson. Pat Garrity tried to cut him off but Kobe blew right by him leaving Howard alone at the rim as Kobe approached.
Kobe rose up and before Howard even realized what happened, his face disappeared as Kobe threw down the vicious dunk on top of him.
This is a special dunk as it is over a three-time defensive player of the year who has averaged more than two blocks per game throughout his career, though admittedly in his rookie season. Another classic poster for Kobe, this time over a true shot-blocker.
