There is always going to be controversial decisions. Hell, it’s been well over a decade and I can still find people who will argue over Machida-Shogun I or Penn-Edgar I. I doubt Ketlen Vieira’s debatable win over Holly Holm will have the staying power of those contests, but it could end up being the most argued decision of the year as things sit. Personally, I wouldn’t go so far as to call it a robbery, though I did disagree with the decision. Regardless, it gave UFC Vegas 55 a strong talking point for a card that was expected to fade into the background in a hurry.
