There are just way to many variables at this point to definitively evaluate who the best linemen are and what position they should be playing.
- Can Butler stay healthy? Can he play RT? For that matter, can he develop into a dominating RG? He was just average at RG last season.
- Can Bell play LT?
- Can Walker play LT? People have written him off, but the season hasn't even started yet. I think that he needs to be given a few games at LT to see how he does. Can Walker be a dominating RT? He was just sightly above average last season, IMO.
- Will Woods become a good interior lineman? Can he play center in this league?
- Will Levitre become a good interior lineman?
- Is Hangartner a good center? People seem to want to move him immediately to the bench, but he hasn't even played a regular season game for the team yet. Why not see how he does first?
Until some of these questions get answered, it's going to be a rotating mess on the line. I think that it'll be at least through this season before some of these things are worked out.
