Never been an offensive lineman, but I have to believe that so much of the success of an O-Line is dependent on continuity, and trusting those around you. I don't advocate ever overpaying for any player, but at some point in time, the front office needs to take a few chances and make the right calls on some of these extensions.
Dotson has been playing WAY above his talent level in this system. Not sure why exactly, but boy, this O-Line is something else. And Noteboom, he's a conumdrum for sure, but he has shown the ability to fill in all over the line without dropoff.
