Hold up, we don't actually believe those numbers are accurate do we? Dexter Williams has a 45.5 vert? He has a 3.9 shuttle? For perspective, if Dex put those numbers up at last years combine, he'd tie for the 2nd fastest 40. He'd absolutely crush everyone in the Vert. And, he'd have the fastest shuttle (also by a sizeable margin). Basically he'd be the most athletic RB in the 2018 draft and have made Saquon Barkley look silly. Lol, not happening.
Also, the way Nike Sparq tests vertical is the most asinine thing I've ever seen. There is a reason neither the NBA or NFL use it at their combines.
