Yes, I’ve seen video of the footrace between Noah Lyles, the Olympic 100-metre champion, and Darren Watkins Jr., a.k.a. IShowSpeed, the social media megastar whose content often involves feats of athleticism. In one post he leaps over a moving car, so who’s to say he can’t, at the right distance, upset the current world’s fastest man? Lyles, for one.
