I think you're correct that the bears talent and much-improved coaching increases the floor to 6 wins, but the greatest concern is the lack of depth up and down the roster. QB, RB, OL, WR are of great concern with respect to depth and we already know how potentially fragile the defense is, front-line talent and depth, respectively. You can always point to how injuries can derail a season, but as much i hate saying it, the packers always find quality depth that prevents a total season meltdown. Cobb goes down, some steps up, Raji goes down, someone steps up, etc. The bears haven't had that luxury for years
