Neal..of course an NFL player could have a hit like that..many do each year...it's just funny to watch. Also, if you would pay attention to the beginning of the video, the guy is basically getting paid either $100 or $150 to do exactly what he did. The point of that wasn't Kimbo intercepting that ball..the point was him knocking the snot out of that guy...mission successful.
Another thing. Kimbo has never and probably will never claim to be a mixed martial artist. He knows he is a street fighter and has even said so on many occasions, but he makes tons of money off of doing MMA, so why wouldn't he? Also...I doubt many people could do much of that 265 lb tub of lard was laying on top of them.
