Oh yeah and in response to the thread..

I think a lot of this has to do with "rolling with the punches." Mosley, Campbell, and BHop do it surprisingly well for their age. The punches seem to "slide" off of them. This can be increasingly difficult with age as your split second reaction gets worse and worse. A flying fist can do much more damage to a stationary target!

I really like the stuff about the concussions. Look at troy Aikman after someone "broke the seal" on concussions for him it was back to back to back. He seems to have his whits about him while commentating.
