Here is video of Williams at the plate and you can see his wheels to first.

That is, a guy you have to have experience "projecting his skills into the future" once he is fully developed physically. Tough thing to do, but the best scouts peer into a crystal ball to see what a kid like Williams can become. I think the Yankees minor league player development people are going to have fun working with this kid.
