It looks cleat to me. Tom Wilson of the Caps absolutely leveled the Avalanches Nikita Zadorov with a hit to the chest. Wilson glided into the hit, didn't launch himself and hit his target in the chest.
Zadorov could be seen sleeping momentarily on the ice, but he was able to eventually get up and skate off. The announcers lost their damn mind after the hit which is entertaining by itself.
Enjoy one of the biggest hockey hits of the NHL season.
