fair enough...good points...your list is short though...chael has a sub 30% finish rate and many more examples of hollow trash talkers exist..Tito ortiz etc..Not sure of this is accurate. First thing would be to define who is considered a talker besides the obvious one being Conor, I say Ronda is one too. Some finishing rates below
Fedor - 75%
Conor - 90%
Ronda - 100%
Covington - 50%
Rampage - 62%
Kevin Lee - 59%
Ferguson - 78%
I'm skeptical that being a talker has a direct effect on finish rate and it's more to do with style of fighting and opponents.
This is a new era and you listed some new era guys....while not a perfect theory, I think in the past my theory is more accurate...new era will have less and less quiet killers, as the attention whore era is upon us IMO
also I view finishing rate a bit differently than you calculated above...I prefer to think of it as the percentage of fights won by finish or stoppage, losses should increase finishing rate...so conor would have a 79% finish rate and Ronda would not have 100%...Just stating what I meant(my short sentence left a lot of details out that were in my thought, which was poorly worded)
Also my definition of finisher was not complete...A finisher to me is a guy who is always trying to end the fight, even if he is not successful in doing so(this would not end up in a measurable stat but is seen by the educated MMA eye)...I prefer to watch guys going for the finish instead of riding out a decision like Chael/Covington etc...
take care
