I'm sticking with Lewis as my number one guy.
Gatlin (post Vince) is probably the worst runner I've ever seen to run at a high level. Perhaps Crawford could give him a run for his money. What do I know though…they both run very fast 😉
I think Powell does some amazing things at top end speed. I'm not a big fan of his arm swing but his postural alignment and the positioning of his toe-off with respect to his COM is incredible. I don't think I've ever seen another athlete like it.
I always considered Mike Marsh as a "mini" Carl with respect to mechanics. Very similar, just shorter levers, and thus, not as dramatic/stark in his perfection.
