I'm really not sure who among us is the most qualified to diagnose what "raw emotion", "contrived emotion", "spontaneous emotion", or "showing up" really are. Since those are subjective things and are subject to an individual's individuality and makeup, who are we to classify?
If you wouldn't act like that, congratulations, that's wonderful for you. But, I'm not going to hold raw emotion over someone's head. Whether it's Joba, Tiger, Rash, etc., it really doesn't matter. If there's reaction after an "accomplishment", then that's what it is, a reaction.
You, as the opponent [if the case should so happen], have to opportunity to react. So, go out and beat his big mouth!! If at the end you don't, then shut up, pack your bag and leave the spotlight to the better person who went out and beat you.
