So Pudz, Brian Shaw, Hafthor Bjornsson, Zavickas and 8 other guys as strong as them?
The strong men all act like Machida running up to the gorilla and back to tire him out. When hes visibly gassed, one guy jumps on his back which causes the gorilla to go apezhit and gas out more. Eventually they all grab his legs push him up against the fence and toss him out of the cage.
A gorilla is 300 pounds, but all the strongmen who lift much more on a regular basis acting in a concerted effort could lift him up and push him out of the cage.
Give them bats or sticks and the gorilla has almost no chance.
