To equate him to J Webb is a mistake in my view. J Webb didn't play at Stanford and block Andrew Lucks blind side. At no point in his career was he ever as successful as Martin. Further Webbs work ethic and intelligence were question marks before the draft and his bad body language at the Texas vs the nation game turned a lot of teams off on him. That's never been in question with Martin on the other hand. My view is Martin wasn't fit to play left tackle in the NFL. He's more likely an excellent right tackle or guard(he excelled at run blocking in college). Do you think you can play for Jim harbaugh and not be mentally tough? He may have been viewed as soft because unlike incognito, jerry, and pouncey he had a brain in his head and was highly intellectual. As for his drive/work ethic...this is from his scouting report: Martin brings a work ethic that seemed to be infectious across Stanford's offensive line and has the on field attitude you like in your tackle. He also brings a special toughness and has played well through some minor injuries. His teammates say he has a true desire to be the best at his position.
