Week 8 of the NFL season is a good time to pick teams that will begin their slow tumble out of contender status back to Earth.
An example from early in the season would be the Miami Dolphins. The Fins started out 2-0 but have lost three of their last four games—with all three losses coming at home—to drop back exactly where they belong: the middle of the pack.
It's better to fall back to Earth early, as the fall will undoubtedly hurt less. Unfortunately for these next five teams, the fall will come at midseason, just as their fans start to believe their team's success might be the real deal.
