whoa, whoa, whoa. Lets not tear a strip out of the lowely football lineman, why do they always get brought up anyway? Some of the fastest men in the US are football players. And football is a lot more like interval training (half hard, half recovery) lets not get hasty in our discriptions in one of the great american sports now. (Randy Moss 4.0 s at 40 yrds or 9.11 m/s the olympic world record speed is 10.21 m/s in the 100 meter by maurice green) Sorry for the rant it just irks me how everyone calls us football players a bunch of fat slobs who do nothing. Thanks for your time.
