Weights a subjective thing though, it all depends on how he carrys (his body make up... how much of his mass is actual lean muscle etc) it and as you said how tall he is.

He's not that big but he dosn't have a punchers physique... just looks like he's been doing generic weights for the sake of it like most people in a gym who don't train for any particular sport. I don't know that much about MMA, maybe the build suits that but he just doesn't look like a puncher... a guy like Tyson was short and weighed that much but looked completely different
