Manute Bol was a freakishly tall and thin person at his regular weight. I doubt his body could have withstood the hardships of professional fighting anyway, let alone if we was trying to cut weight. As far as Bol making 185, that is unadulterated horseshit. I'll believe it when I see it.
For comparison purposes, Gheorghe Mureşan is also 7'7" and he weighs more than 300 pounds. Although his proportions definitely aren't as freakishly terrifying as Bol's, Muresan isn't carrying around a lot of extra bulk.
7'7" Manute Bol looked unhealthy at 225 pounds, but that's not even what we're talking about here. We're talking about 7'4" athletes being effective fighters at 135 pounds or less. In one case the guy is less than 100 pounds, and those situations are completely preposterous. The engine should be applying much larger negative modifiers, because people with those proportions should barely be able to move, let alone fight.
