No. 3 - Anderson Silva Barely Escapes With Victory Over Chael Sonnen
We've already touched on the impressive MMA career of Silva, but that doesn't mean everyone likes him. At one point fans were growing tired of his boring, lackluster performances (even though he was winning), and were rooting for him to finally lose. Notorious loudmouth Chael Sonnen was well on his way to making this happen at UFC 117, dominating Silva for four and a half rounds, when Silva miraculously reversed his fortune by getting Sonnen in a triangle choke. Silva defeated Sonnen via submission with less that two minutes left to go, retaining his middleweight title yet again.
