Ok, before I type the rest, I want to say this.
I am NOT trying to take away anything from Chris. It's a complicated situation for me. When Chris won the first time, I jumped out of my seat, cheering and celebrating. I think Chris was winning the second fight as well. I just wanted to see Anderson get started(he is a late starter) and watch a fight. I wanted a definitive finish, with purpose and full intent behind it. We didn't get that. But, Chris won that fight. I personally wish they could fight today and act like the second fight never took place,.. but not to discredit Chris, but to justify him.
Me saying that the result was a fluke, is me looking at it from a non-bias point of view. People that are trying to say he did it on purpose and are insinuating he knew he was going to break it, irritate me.
Now,.. lets look at the definition you posted.
- unlikely chance occurrence, esp. a surprising piece of luck.
The first part I made bold, is the actual definition. The second part is an example/sub-explanation.
The break, was in fact, an unlikely chance occurrence. Out of all of the leg checks in UFC history, breaking the kickers shin has now happened twice. This makes it an EXTREMELY unlikely chance, statistically and therefore is the meaning of the term.
He didn't do it on purpose(break the leg), but that shouldn't take away from his performance either. Crazy Silva fans that try to discredit him, by calling it a fluke, are using it in the wrong context. But from a purely unbiased point of view, it was in fact a fluke.
