Economics of Mixed Martial Arts Training

This is from bjpenn.com.

Firas Zahabi is the head coach at Tristar Gym in Montreal. he has worked with Georges St. Pierre and number of other UFC champions.

Here he is explaining why Ronda Rousey's problems as a standup fighter might not be entirely the fault of her coach. I actually think her coach is a big part of the problem, but I liked Zahabi's analysis of the problem, especially the last two sentences.

“The reason why a Ben Askren or a Ronda Rousey’s striking usually — not always — doesn’t hit that high level, is because they’ve spent so much time wiring their brain and their body and their nervous system to fight in one particular way. It’s opportunity cost. Every time you do one thing, you’re costing yourself in another.”
