Big guys can run fast…no doubt about it…at least for short distances. I worked with a guy, Jeff Laynes, at one of this year's high performance centers and he had just run a 10.1x (windy I think; 10.2x legal) and he was as big as an NFL running back. It was striking how big this guy was. My question is, how much faster would he have run (and the guy you mentiond) if they were 190 rather than 200+. Also, regarding Carl and Lutz, I have no comment on Lutz. Never seen the guy. I have seen Carl both during and after his career. He was skinnier in the late 80s than he was in the late 90s when I saw him and I can't possibly believe that he was ever over 200 lbs. Are we talking about the same Charlie who said that Marion and Tim were so talented they didn't need to take drugs.
most big guys who are fast or also taller 6'2-6'4, i would love to see someone like maurice drew 5'6 210 run 10.2 100m. lol
