How good would the Packers be if they had a O-line?

Just read on the Packers website that Mark Tauscher was in Green Bay and might be coming back and Clifton will be back after the bye so, hopefully that would help. Oh, bye the way Rodgers is awesome and if Favre was Green Bays QB this game isn't even close, he would have been sacked 10-15 times-not as mobile. How is it that the Vikings defense is so great yet gave up 424 yds. only won by 7 after all the sacks, penalties and turnovers by the Packers and how do the Vikings only get 2 penalties for 10 yds.
