How can we when the O line can't open a hole? I don't care what O Gus tries to run or what QB he decides to use, nothing is going to work with this O line play. You could throw Cam in there and he wouldn't be able to do anything behind that line.
Also fwiw I agree that making sure the O line issues ultimately fall to Gus. If he can't find someone to fix the problem he needs to go.
