Totally agree on the position as there
potentially may be more value at guard than tackle in free agency this offseason. I say potentially because many things can and will happen between now and March when free agency begins. That said, if Scherff is not an option I think Joe Thuney from the Patriots is an absolute steal. Now, the Patriots would be wise to keep him, but if he ever hit the open market he is worth a top 5 salary for his position.
BTW, I agree on Littleton. Having no solid ILB on your roster in early March is a horrible way to start the new year.
