It also helps the ball go farther if there's something between the grass/turf and the bottom of the ball. I used to kick in high school and even something as thin as a poker chip helped.
Aaron Donald over Daron Payne kind of invalidates the whole exercise
Adamas over Hill is really dubious
Jaire Alexander and Hufanga should probably be on there
Josh Jacobs is like the 5th or 6th best RB in the league
