I’ve heard this, but why?
For a WR, wouldn’t we be more concerned with long speed? Once they get off the line it’s about how they accelerate to top speed and run by people. A ridiculous 10 yard split seems like they have a really nice start, from a 3 point stance on the ground, like a track athlete.
I think 3 cone is the best metric for WR and pretty much every position. Dotson didn’t perform well on that, though.
