Yes it does, thats why the prime Mike Tyson who demolished Michael Spinks in 90 seconds would decimate the 147lb Floyd Mayweather with the first punch he landed 20 seconds into the fight.
Tyson trying to catch Mayweather would be like you trying to catch smoke with your hands mate. Road Runner > Wile E. Coyote.
You are missing the point. The guy in the video said Tyson was crazy fast at 220lbs,imagine if he had taken off 70lbs. His speed would be bizzare and in that case speed would kill. I don't necessarily agree with that logic, but it can be argued that way.
This is why we love you. Had you offered the full fat Guoc option, she'd have been all over you knob.
