1st off let me just say. I agree that as long as either of the SHR cars have a shot at the chase nothing will be done about their teams other than maybe minor changes to pit crews.
With that said Any CC from a championship caliber team is a step up for the 39 team in my opinion. Unless Newman hated Greg Erwin, I would take him in a heart beat. I think Ryans hard driving covers up a lot of what TG actually is. I am not sure a lot of people realize how bad the #39 team really is. If Ryan makes the Chase, TG job will be secured another season, despite what (I think) should happen.
