When the Buffalo Bills lost last week, they experienced a slight dip in weekly NFL power rankings. Now that they're back on the winning track after a 31-24 win over the Philadelphia Eagles, the Bills are obviously on the upswing again heading into Week 6.

We've seen Buffalo ranked as high as No. 4 in the NFL, with Mike Florio of ProFootballTalk.com doing the honors. Peter King of Sports Illustrated and the panel at ESPN.com rank the Bills at No. 6, while the panel at NFL.com have them at No. 7. Even the players ranking the Bills a touch lower - FOXSports.com's Brian Billick (No. 8) and CBSSports.com's Pete Prisco (No. 9), for instance - remain bullish on the Bills.

As for next week's opponent, the 3-2 New York Giants, they're falling a bit after a surprising home loss to Seattle. Still, the lowest we've seen them rated in these places is No. 16 (Billick), and Prisco has them at No. 11 - just two slots behind the Bills. Insofar as matchups go, the Giants may prove to be the most even matchup we'll see for the Bills this season.
