I agree about Lang, while I think Sitton had a down year I still think he is our best lineman with Lang being second and Bulaga 3rd.
I think when Rodgers talked on his radio show about mentality he was talking a lot about the line because as I watched this year a lot of times they just looked soft as pudding. I mean I remember a few times when I watched Sitton just get pummeled, and I believe he was a culprit of a few too many flags(I could be wrong)-I just remember thinking "I thought this guy was a pro bower?"
I also agree with you about EDS, I've never seen him as a long term fix as he is another guy can be completely overmatched at times, although I saw more of this when he had to sub in for a guard position.
Lastly, I agree with you about Sherrod and Datko, I'm still a little hesitant on Datko but I don't doubt his potential.
