Well-I don't feel like the oline has been given a chance to gel as a complete unit is all. They basically have three new starters when you factor in a switch of positions for the bookends. One stiff we can all agree on is setting Doug "Free", but I would be comfortable bringing back the rest of them with added depth. Livings has played well. Smith has been a little disappointing, but he's still one of the youngest left tackles in football. Bernardeau has shown at the very least he can be versatile and hasn't played next to a consistent center all year. Yes, I am still optimistic on Costa, so shoot me. The Cowboys have a history of giving up on young players early and Costa has shown he is improving. Who would you replace him with? Khalid Holmes who was beaten like a rented mule against Notre Dame? I guess Barrett Jones possibly, but personally I would rather spend the first pick needed to draft him to help the dline/pass rush which is ancient than spend a first rd pick whose ideal NFL position is up in the air. If Costa can make it back with four games to go, than everyone will be able to make a better judgement on the oline. If he sucks, than I will happily switch off my happy fan....until than I am still in his corner and remain hopeful the oline is better than average.
