That last point is a myth. They didn't have a running game in 2006. Sub 4 yards per attempt. Pathetic. The D can be dominant. Contrary to Peter King's absurd opinion, they were devestated by injury in 2007. He wouldn't take much to vault them back up to dominant status. Likewise, while they currently don't have an offensive line, there's no reason why by September 2008 they can't have a decent one, and that is going to be the most important aspect affecting your third point. The running game might not have been great in 2006, but it was still somewhat existent. Enough to make teams somewhat respect the PA pass. Also considering the fact that the Bears don't figure to be major players for any top FA lineman, and todays commment by Angelo in the paper that he prefers veteran olineman(basically indicating that if an Olineman is drafted high, he won't start), I think a capable Oline by next season is a pipe dream.
