So I know some people will say that there is no luck, and these shots are planned. I'm defining luck as the likelihood that the performance can be duplicated again/repeated. JDS vs Cain GSP vs. Matt Serra Masvidal vs. Askren Mcgregor vs. Aldo Bisping vs. Rockhold And so on and so forth. I think the one for sure that was the luckiest was probably JDS vs. Cain because at least we got to see it two more times to know just how lucky it was that JDS landed that punch in their first fight. My personal bias is for Bisping vs. Rockhold though. I thought Rockhold would be a dominant champion for years, and at the time I thought Bisping hit the luckiest left hook in UFC history.
