I think this video mainly reveals how we'll attack Dallas in the running game. Though according to Winston 3-4 is tougher to play against in a zone blocking scheme against then a 4-3. According to Winston, Shannahan likes to arrange scrimmages during camp against 3-4 teams so wouldn't be surprised to see us scrimmage the Steelers especially if we go Carlisle for camp.
For those who don't know Eric Winston is an offensive tackle for the Houston Texans.
