Are all the best American Boxers in the NFL and NBA?

[Taeth]

Boxing more brutal than NFL

i rather be in a ring with Wlad than be on a field with Ray Lewis.

plus you only take the hits come fight night, which comes at the most once every 3 to 4 months, not like football which is pretty much weekly

So boxers don't spar at all? Football is a lot harder on the body, but not even close on the brain, boxers need to stop fooling themselves that its not the case.
