What we don't know is how he grades out with coaches. We see a couple places, maybe a game where he seems to have not played well, but what was really behind that? Was he 100% healthy (well, 90% anyway)? What did he do that was really good that we didn't see? Coaches go in and look at every play in every game and assign grades, because they know what was expected of the player and what he did. We look, and we think we know, but we only see them for a few moments here or there usually. We see them give up a sack, or make a big block on the outside when they pull, but not every play. All I mean by that is I don't know enough about what he did right and how he grades out compared to his teammates to say whether he's the place we need to upgrade. Obviously, we need to do something about that line. Not being able to make a yard on the ground when we need it, or letting Romo get killed in the NFC Championship isn't going to take us where we want to go. I know Big Len and Gurode made the pro bowl, but not sure they deserved that. We can't come back with exactly the same starting line next season. Our kicker and our O-line lost games. It's easy to point at Kosier, since Gurode and Davis went to the pro bowl, but not sure if that's an accurate ordering of problems on the line.
