The NFL is a week-to-week league, and so much can change after a set of games.
For example, the Buffalo Bills came off a dominant Week 8 victory over the Oakland Raiders, only to lay an egg on Thursday Night Football in a 34-21 loss to the New York Jets.
On the flip side, the Washington Redskins were outplayed in a 33-19 loss to the Dallas Cowboys, but then they pulled off a huge 17-14 upset over the Seattle Seahawks at CenturyLink Field on Sunday.
We'll see what happens in Week 10, but until then here's a look at some projected power rankings following the Monday Night Football contest between the Detroit Lions and Green Bay Packers (the pick here is that the Pack win).
