This would be a tough, physical fight. I think Jirov is the more talented fighter but it wouldn't surprise me if Cooper caught him.
I think Jirov needs more head movement to be the guy with his hand raised at the end. A lot more head movement is needed against this opponent & the punches he throws. That and the stepping on the gas and going forward with that defense. Just do not like it and there are other cruisers capable of giving him major problems as well. He did the best with what he had but there are landmines out there for him.
