The bottom line here is that we just don't know yet and won't know until a couple of games into the season. It is conceivable that we could have better personnel and still be worse because all the new parts have not gelled. Don't underestimate how much offensive line is a team endeavor.
That's why I'm hoping the new OL coach doesn't do what the previous two coaches did by tinkering with the personnel grouping all through training camp.
