He has two undrafted OT's though. Thats the real problem
Not to mention his Center. Just because he's from Yosemite's alma mater, doesn't make him the same.
The real problem is the lack of continuity and these guys haven't built that trust necessary for an OL to become a great unit.
I would like to see every team toss their two OT's, and the Cowboys had a very good tandem, and add a rookie Center and see how well their offense performs.
Part of Prescott's success so early was that OL and run game he had that so few rookie QB's get to play behind. The QB was the least experienced in the group, now that has reversed except for Martin.
Here's where having McC should pay off because he always had OL challenges in GB with his lineup. Any HC that can win a playoff game with 5 G's on his line should be able to make this work.
