We need to define elite speed if you are going to use Alloway as a comparison.
Damian Alloway is quicker and agile than fast. He is similar to Theo Riddick. He is going to juke you out of your shoes, but he isnt going to ever be considered a blazer.
Alloways accelerates in and out of his cuts good, but for being around 5'8, he needs breakaway speed. He is similar to Ryan Newsome in the 2015 class. He has the ability to get loose based off his agility, but not pure speed.
CJ Sanders has pure speed. Sanders COD is not on Alloway's, but he is able to change direction without losing too much speed.
Alloway will need to prove he can run routes as well. He can create the separation with his ability to get in and out of breaks, but will he have the speed to consistently get open and get loose? It's a valid question.
I mean a kid running a 4.5 and having a 4.36 shuttle isn't screaming speed or even agility. I'll give him the agility bc of his actual film during a game, but his film doesn't show elite speed.
