People just underestimate the skill aspect.
There are all kinds of ways to gain leverage in judo, muay thai, wrestling that the average person just has no clue about. Even Matt who trains regularly admits he would be at a major disavantage vs Ronda in grappling and this guy would probably kill 95% of guys, think about that.
This is actually also the reason a shitty MMA fighter could kick the ass of the biggest, toughest guys who aren't skilled in any fighting disciplines.
You might be right. Holm is 34 years old. Almost past her prime already. The only other girl that is really good atm IMO is Amanda Nunes, and she's almost 30. I really like Joanna Jedrzejczyk, but she's 115 lbs, but exciting to watch. Probably has the best stand up in women's MMA next to Holm.
