The Lions offense could be good, but again, their line isn't very good and they still won't have Kevin Jones back there---it'll be Tatum Bell who is an underachiever. I think there offense could be Top 5 if they get some production from Bell running the ball. However, I don't think they'll win 10+ games, but who'd have thought the Saints would do what they did?
The Bears won't be as much a factor in the Lions doing well as the Lions Oline and Defense will. I don't think the Bears will have nearly as good a year and a team steps up, could overtake Chicago---Mike Brown will be hurt, Tommie Harris will end up hurt, those are two known things with that defense. Plus, Grossman is awful at QB. I don't think it'll happen for the Lions, but whom am I to say they can't turn it around in one year?...especially when I hope the same for Miami.
