He can absolutely play LT. He wouldn't be elite, but he would be league average at an absolute minimum. He could probably make the Pro Bowl
As far as a lack of foot quickness to mirror speed rushers. This is a fallacy that has been going around here too muck. I definitely didnt see that when I keyed on him last year at LT. I watch him shut Brian Burns and Khalil Mack. If you stonewall those guys consistently, you can play LT in this league. He isnt going to be as good as Guyton is playing, but he definitely has the traits to be a quality LT. Go watch him block Burns in the finale last year. This lack of foot quickness needs to get shut down
