Shell shocked 

Traumatized.

The linebacker from Nigeria took the receiver's helmet off his head and positioned it so that when he started to stomp on his head, it crushed his head, as he made a sound kind of like Solomon towards the end of Blood Diamond (the shovel scene) as he did it. He didn't realize that most people playing football weren't doing that, this guy really wanted to win, and he was trying to give beyond one hundred percent all the time. It was always life or death for him, since he had been shell shocked since he was a kid.
