No, i was just giving an example of how speed is a very big factor.
This was in response to itadakimasu saying he was a beast, but only weighs 140lbs.
Just pointing out that weight has little to do with that.

It doesn't really matter how big you are, a 32mph punch from any grown man ( or woman ) on the nose, chin or even temple and liver, will hurt a lot if it doesn't disable you from continuing the match, which happened to Kimbo, though in this case the punch was prolly slower, but had more weight attached to it.
