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.
