To see if he is always a dirty player.
Don't get me wrong in no way am I saying this was right... In no way!
But had something similar happen in my family about 10 years back.
We were playing a catholic school in the playoffs that had a huge 300 pounder that had a D1 scholarship waiting on him.
My nephew who was lined up across from him who weighed maybe 210.
My nephew was mouthy & I can only imagine what he was saying to the big dude, in my mind I'm sure the N-word was used quite a bit.
Finally he ( big dude) had enough & attacked him about 10 yards out of the play, luckily he was able to get away.
Later when I asked him about it he said "I was trying to get him kicked out of the game" (it didn't work, just a flag)
I guarantee you that nobody would have been surprised on our side if something like this would have happened to him.
Again, I'm not saying it was right in any way but it does happen.
You couldn't possibly know the whole story with only half the facts.
