I don't really watch football but has there been any hits comparable to this in the NFL ?

Id say NHL because of the boards,

but as you say bias hockey fan

Soccer ofc, the impact is so big the victim goes flyin

People sure can dive far.

Sean taylor was the hardest hitter made terell owens sit the bench

Ouch.

Isn't this hit illegal though since it was helmet to helmet ?

so many dirty blindside hits

wouldnt it have to be nhl? if we assume the players travel at the same speed, getting hit in an open field allows the victim's body to travel as he's being hit. If a hockey player smashes someone against the wall, there is no movement-- the same speed would feel harder in hockey

The board is not solid like a wall, it's built to absorb most of the impact. That's exactly where you want to be it actually.
