That's true.
Looking at the opponents they have after Detroit though... I guess it'll come down to Arizona's passing attack, which should be crazy against a Williams'less D-lne.
The Falcons I'm not to sure about. They seem like a solid team, but nothing spectacular.
The Giants game will depend on how the Giants will play these last couple of games. I asume they'll have a play-off spot and just put a back-up team in there.
It does indeed not look to great for us, but if there's one team that can screw it up, maybe even against the Lions, its the Vikings.
What everyone's forgetting though, is the Bears. They have a rather easy schedule and we HAVE to beat them to get there. They could go down against the Saints with their great passing attack, but with the Saints losing McAllister and a D-lineman, you never know.
