This. Trying to stop him with a body shot is asking to receive a savage beating after brief initial success.
Wrestle him contain his attacking and have some sort of plan besides a Mowgli run away and occasional swing
A lot of people are disagreeing with you TS but I am on the same page. His biggest weakness he's shown has been submissions but last night his liver got exposed. He was hurt with a body shot at least 3 times, I've never seen that in a fight. Future opponents may be able to capitalize on that and turn it into a submission or takedown anyway.
You know what they say, punch a blackbelt once and he's a brown belt. Last night, a guy who was a purple belt (up until the end of the fight... then he was Matt Brownbelt) punched a black belt a couple times - 177 to be eact - and dominated him in MMA BJJ. Infact, even while Silva was still a blackbelt and Brown a purple, he showed good MMAJJ defense and warded off a rear naked choke. Dude is legit on the ground in my book, and I am a one stripe white belt so clearly have a lot of authority.
