You guys are clutching at straws. It's pretty clear that he was hit in the head and was already out of it on the way down. Buddy's best bet to get off is to try and prove that he didn't have the option to tackle. But he clearly did, so I'd say he's going to lose the appeal. You might say it's taking the hardness out of football, but those are the rules (at the moment). Smart thing would be to tackle them when they have the ball, bump them when they don't.
