Your first sentence is very true. A healthy Urlacher, Harris at the FS position, and Peppers on the DL could make all 3 levels of the defense better. A real OC, healthy Forte with a backup, full year of Aromashodu, and OL playing in their natural positions could mean the offense could be better at all phases. There is not a single unit where you can say the Bears definitely were downgraded. And on the positive side, the team was 7-9 and without some costly TOs and defensive lapses late they could have won 5 more (GB x 2, SF, ATL, PHI). On the negative side, they need a whole lot to go right in order to be a playoff team in a tough division. They are counting on a lot of 30+ year olds at key positions (Urlacher, Kruetz, Garza, Peppers, and now Briggs will be 30 this year). They are counting on players who are huge injury risks (Urlacher, Harris, Tillman, Bowman). They are counting on a lot of young guys stepping up and becoming quality players (Bowman, all the WRs, Williams, Forte, Omiyale, Asiata, Manning, Anderson). That's why I said that the Bears are the iffiest team in the NFL right now. Not all the above will go their way, but I think if the right ones do go their way, they are very close to being a really good team. But if those same ones don't go their way, they are very close to being one of the worst teams in the league.
