Totally wrong.
Greene, Carter, BJ, McTear, Simbine, ADG, Su, CC, Cason, Mullings, Frater, Boldon, etc etc etc etc
Tons of those guys were/are as fast or faster than faster than Lewis.
Witherspoon was 6’5”, he wasn’t amazing.
The 100m is a composite. Taller guys (Bolt, Obikwelu, Lemaitre, Lewis, etc) have a lower first half ceiling, and shorter guys (Greene, BJ, CC, etc) have a lower second-half ceiling.
The most important thing in the use of PED’s is to compensate for deficiencies—tall guys in the first half, shorter guys in the 2nd half. The key is to look for athletes with an exceptional half—eg Bolt in the 2nd, BJ in the 1st—and supplement accordingly. It’s a system as old as time.
The vogue now has been to find those intrinsically better in the 2nd half, but only because guys except CC have forgotten how to accelerate well. The fashion before that was BJ, Mullings, Greene, Frater, etc who had a great first half, then the 2nd was bumped. BJ’s Seoul 2nd half was great; Greene’s was always great; Frater used to run long 2nd’s on WR relays with the best ever running other legs!
There is no intrinsic 100m benefit from height. Which direction supps better is a function of both supps and enforcement environment.
The best seems to be the mid-range guys like Gatlin, Bailey, etc maybe up to Powell and now Thompson, who use different amounts of broader-spectrum tools.
Each era is different. Great height is no advantage. 6’5” or 6’6” is imo the max profitable, and maybe 5’7” or 5’8” the min. Between those 2 values, you play. The he better you are at the game, and the more competitive advantages you have, the better you end up. Bolt had the biggest competitive advantage in the history of sprinting, all the way to the top, which is the only reason he has ended up with the fastest clocking.
