Its old but you rally see were they go wrong at Hooft and ROckhold especially. Nothing bad to spar hard from time to time but go like this is just unnecessary. You can really learn from the greats in KB.
Ramon Dekkers was a monster. He did his pad work at a very high power level, did drills at a high level but often sparred easy because it was to develop skills (timing, distance) and not breaking someone or himself. The same all the great Thais do.
MMA still has a lot of this nonsensical macho attitute and ROckhold is the posterboy for it. At least he was. Meat day at blackzillians was the perfect example. Dumb beyond dumb.
