With the book behind us, weekly FO columns on ESPN.com return. This week, we look at teams that lose a star offensive lineman. The numbers were pretty surprising -- as a group, teams that lose a star lineman don't tend to decline. For every team like the Chiefs of the last couple years, there's a team like the 2000 Vikings or 2006 Saints. Adding a top lineman? That's a different story, one that will give Jets fans a reason for optimism.
