Hassan Whiteside Stares Down Knicks Guard Justin Holiday After Poster Dunk

Midway through the second quarter Tuesday night, New York Knicks guard Justin Holiday tried to derail a dunk attempt by Miami Heat center Hassan Whiteside.

It didn't work.

Whiteside tested the rim's strength with a monster slam despite contact. After the whistle, the big fella stared at Holiday in disbelief.
