I don't think they're starting from scratch by any means. If you assume Evans and Edwards will take positive steps developmentally in year 2 (and I do) and that Whitworth is back at LT then I think you try to upgrade one spot (LG), maybe two (C), while improving the overall depth. To me improving depth can be done by upgrading the LG spot and moving Corbett to 6th man. Then Noteboom is the 3rd tackle, etc.
