I’m in the camp that believes track speed is different, but this guy is so elite I don’t think it’s much of risk.
I do believe a guy that runs a legit 4.4-4.5 and is an elite route runner is better in the long run, but it doesn’t matter.
Also, what if he can on special teams or even ended up being on defense. Take the best athletes available and figure it out later. 42” vert is stone cold crazy.
