A good point. I was being lazy with word "strength". IMHO, NFL running back are probably the best overall athletes, but of course you can't deny that most of the best shot putters of the world have come from Central and Eastern Europe.
I guess my point is that we shouldn't be afraid of being labeled racist because we choose not to have our analytic scientific points of view muzzled. I mean, for God's sake, we all know that 8 descendants of West Africa will be lining up this August in the 100 meter final in London.
