Well, first of all I didn't say he has bad feet, I said they were not great, and if you care to actually watch hundreds of snaps like I have instead of citing some random post with 7 clips maybe we can have a real discussion? I can show you 7 clips that make him look terrible. He has good feet, not great feet, Like I said, his real upside is at guard. He can probably develop into a good right tackle. If you're going to overcome a lack of length at tackle you better have elite quickness, range and feet. He has none of those.
Put on tape of Paris Johnson and Skoronski. There is no.comparison. Johnson has all the traits needed to be a top flight NFL tackle. Skoronski has all the traits needed to be a top flight guard. You can just pretend that arm length doesn't matter, but it absolutely does. There is a reason that 99% of NFL tackles have over 33 inch arms.
