He was definitely bitten, but it was at least somewhat his own fault. I don't know what the bunker randoms had to say to the on field random, but if they said something about the forcefeeding aspect of the tackle I could kind of understand it. I agree, the situation of the game was a factor, but it is impossible for sure to tell how much of a factor, same as the question of IF the bunker randoms deemed that some of the fault was the idiot who decided it was a good idea to headlock a guy around his mouth, if it was a factor, it is impossible to say its weighting.
