I didn't say he hit him high in what you quoted. I don't think he necessarily hit him in the head. But, that doesn't change the fact it was after play had stopped, was an illegal shoulder charge. And was a heavy hit.
Chad must of been thinking gee how nice of Ponga to just stop playing and look off somewhere so I can smash him. Ponga was also in motion but managed to come to a complete stop AND have time to look at the ref, then turn his head back to look at Townsend before he hit him.
For mine, Townsend made the mistake a moment ago and was p!ssed, he was looking to put on a big shot and in his single minded action didn't pay any attention to what was happening around him, or in front of him, or even to make a legal tackle, and smashed Ponga. It was reckless of him to just ignore everything else and smash him deliberately using a shoulder charge. Late, reckless, illegal tackle even in general play. No brainer.
If this isn't a send off, pretty much nothing will be.
