I think it depends on how well everyone else plays. If the team plays well, I think Fowler can be a benefactor himself and contribute. If the team doesn't play well, I don't think he's the kind of guy to step it up and take the game into his own hands like Parsons. But if all other cylinders are firing on our defense, I think Fowler can chip in and our line will be like rotating hungry hippos.
Like speed says, he won't be the focal point of any offense, so we can maybe even move him around and have packages with Fowler, Parsons and Williams all on the field at the same time.
I think we need to keep as many lineman as we can keep though. We can't forget about playing the run and our 1st and 2nd down guys.
