Injuries, suspensions and deactivations dominated Week 2 in the NFL. If you're looking for good news, there wasn't much of it before the games started. But once kickoff came around, Cleveland and Buffalo brightened things up with surprise wins. But the bad news continued in Washington (both Robert Griffin III and DeSean Jackson left with injuries) and for the New York Giants.

What changed in Week 2 that will affect the weekly power rankings? A lot. Injuries, surprises on the field and deactivations due to off-field issues all factor in to this week's movement.

At this point in the season, power rankings aren't yet set as much by record, although that does factor in, but we're still looking at the mixture of preseason expectations, each team's potential and its play thus far.
