yeah, a lot of room for development and improvement. He has the talent and upside needed to be a good left tackle. Sometimes I look more at the natural talent than polished work as, you can't coach the talent needed at a position to excel. Whereas, good coaching can improve other stuff. So basically can be improved on a players progression and what is it. Work ethic is the other thing, but doesn't seem he lacks that. As that can go against a players natural talent even if his weaknesses are coachable, if he's not self motivated.
