Yeah, if the lines both go south...

If they start the season with Jordan Morgan on the bench (i.e., no upgrade from either Walker or Rhyan)...

AND

If they don't get a much better performance out of the front 4 on defense (at minimum, take that unit's best performance last year and see them play that way for 17 games instead of a few)...

Then I could easily see your 7-10 scenario playing out. I just think (hope?) it doesn't go that way...
