As long as that offensive line can keep Cutler upright, between Marshall/Jeffery/Forte they have the capability to put up 500 points this year. Add to that a relatively weak division (they should go 3-1 against the Lions/Vikings, at least), a relatively weak AFC East (again, likely 3-1) and eight other winnable games, I see absolutely no reason why they can't go 10-6 and make the playoffs at worst, potentially beating Green Bay both times and securing the division at 12 or so wins instead.
Cutler has always been underwhelming, but all the pieces are there for him to have huge success this season. Yeah, the same might have been true last season, but Cutler has never exactly struck me as a fast learner and the second year under a new scheme is usually far better than the first. Jeffery is outstanding, Marshall and Forte have always been great, so the rest really lies on Cutler's shoulders. If that offense is as good as it was last year, or better, there's no reason they can't make the playoffs.
