My thought is that the D will remain solid with a few learning bumps along the way.  We badly need a talent infusion at the LB position.  I'm in the minority on this board that feel Urlacher was below average last year.  Also, looking at Briggs, I found him to have lost a step.  Both of our star linebackers will need upgraded in the next couple of seasons and Roach has hit his talent ceiling. 
  
On offense, I expect the same thing I expected last season.  That we have a learning curve to overcome with the OL, as I expect at least a 40% turnover, again.  The offense won't be good out of the gate, so they will have to ride the fast start the defense usually starts the season with.  If our O is top 20 by the end of the season, we may be one of the hot teams going into the playoffs.
