Gibbs assaulted the Nova player in the head in the heat of the moment. It wasn't accidental. The first swat by Gibbs was accidental, the second swat was clearly an intentional elbow to the face. If you show the video to100 people, 99 will agree that it was not accidental.
I agree with Dan. Hard feelings towards Gibbs and Sina do not serve any useful purpose. I won't go out of my way to root for them, but I won't malign them any more either.
There is no way anyone could watch that video at the 37 second mark and think he was trying to do anything other than clobber Arch.
