Football players aren't trying to knock each other unconscious. While it does happen, same with hockey and other sports, that isn't the intent of the sport.
If those two players were friends off the field then there is no way he would go helmet on helmet like that.
If you step on a football field there is nowhere near the risk of brain trauma as there is in mma, there is no comparison.
