Last year, before the season began and when it was clear that Trent Williams would be out for at least several weeks, there was a tremendous amount of hand wringing about how terrible the team’s offensive line was going to be. How could (former Pro Bowler) Donald Penn be any good now that he was 36? How could the “terrible” Ereck Flowers salvage his career and become a solid option at guard? For some, these proved intractable questions. For others - those who took a deep breath, stepped back and looked at the possibilities - the future appeared less disconcerting.
