There are some really stupid people who continue to raise it, many as a way to bash Jones (who I hate) but beyond that it gets the deserved face palm.
I will say again that the ideal build for MMA for DECADES was seen as the more stocky grapplers build. No one, NO ONE, was saying, uh-oh here comes someone tall and lanky, the division is now fucked as this guy will dominate. That is because everyone expected that guy to get bullied, taken down an submitted or GnP by his stockier more powerful opponents.
What skill does it take to be stocky and powerful (Cain, Fedor) to simply muscle in, drag someone down and drop hammer fists? If you want to play this stupid game it is far easier to argue the grapplers build takes far less skill and that is why it has had more success.
Instead amongst thousands of wannabe MMA fighters you get two break throughs at the highest level (Jones, Anderson) and instead of recognizing that it is that they have a super high level of skill that allows them to negate the strengths of others and THEN impose their game you want to pretend that the Kendell Groves and Diabates of the world, should have easily been able to be dominant champs as that frame does not require skill to get their.
