Early in the game Dawkins got called for a unsportsmanlike, which killed a drive (the refs erroneously called it on Williams).
i just re-watched it. The defender spun and jumped up, and right when he jumped, Dawkins pushed him in the chest and pancaked him. It was a great and clean block, and was largely caused by this guy jumping up. Dawkins then fell forward.
Dawkins literally did nothing wrong.
