Not as annoying of an excuse as many others like Shogun, Nog, Ortiz, etc. But I don't know why fighters are like "I lost because my vision was blurred". Machida "I lost because Bones hit me in the forehead". Just say your opponent fought the better fight, or don't say anything at all. As much as everyone hated him, did you hear Lesnar say stuff like "I wasn't 100%", "I was doing fine until Cain caught me and I couldn't recover".
