Haha, there's no such thing as a good excuse. You can get kicked in the crotch by Sebastian Janikowski, a loss is a loss, I'm sorry to say.
Somebody once said that you can give a good excuse for every loss Arona had.
Fedor - He did very well, many people think he won, and it's FEDOR.
Rampage - He was winning the fight and was knocked out with an illegal headbutt.
Shogun - he was tired after going the distance with Wand.
Wand - split decision. Could have gone either way.
Sokky - Arona had Dengue fever
Still, they're all valid points.
I'd never heard the dengue fever defense for the Sokky fight, but I think "he got punched in the face really f*cking hard" is a better explanation for why he lost.
