I think your main idea is bang-on Wade, but I disagree about one thing: we clearly have the better O-line. Perhaps I should say, more accurately, we have more to work with than the Vikings.
Sitton is a stud. However, Wells has been outstanding. If McGinn is to be believed (no reason for him not to be in this case), Wells gave up his first sack (technically half a sack) since Week 7 of last year. He has done a solid job since taking over for Spitz last year. He is also pretty good in making line adjustments to blitzes.
We also have Bulaga, who held up pretty decently matched against Orakpo most of the game yesterday. Considering this was his first action at RT, it's hard not to feel comforted by having him as a back-up for Clifton or Taush.
And for all his faults yesterday, Clifton was okay minus the major blunder against Orakpo in OT. However, that blunder itself may very well have been the result of Clifton not hearing the snap count, because it's unlike him to totally not move and let his player get by him without even making an attempt to block him. In other words, he still has something left that gives us an adequate option at LT.
Colledge is Colledge, so yeah, but we do have Spitz behind him, who has been solid at RG and shown he is a decent starter. I wonder if he would have pushed Colledge more were it not for the fact he was returning from off-season surgery.
McGinn made an interesting point: Rodgers seems to be regressing and that is costing us sacks. He pinned 2 sacks against the Skins on Rodgers where he either had happy feet and moved into the sack or where he held onto the ball too long. Considering Cal2GreenBay's post about Rodgers less than impressive fundamentals, I'm beginning to think beyond O-line whichever team's QB can manage the O-line deficiencies best will have a shot at the playoffs.
