He is now.... That's why I'm saying you (and Jacob) are wrong. His wrestling / BJJ skills are much better as of that last fight. I don't agree that GSP's bread and butter was wrestling, however. The detail you heard in the video about GSP wrestling with the canadian National team is evidence of himself wanting to be well rounded. But His original martial arts style is Kyokushin karate and is definitely more known as a stand up fighter. Anyway Yes , it takes years of training to hone skills and not sure where I said otherwise
