He has started LT for the best O'line the last 2 years and is only 20.
DJ Fluker who was selected 11th overall last year was the RT for that line and played well as a rookie last year.
I like Zack Martin, but he projects best as a Gaurd. IMO Kouandijio is the better OT prospect. He also has the biggest upside of any OT not named Greg Robinson.
I would love CK at #19 and allow him to play RT opposite a FA LT, shoring up this line for years to come
