What's that saying? Nobody knows anything? I think we learned that this week in the NFL, as reflected in the huge shifts in the Power Rankings for week two, starting at the top. 3 of the top 5 teams and 6 of the top 10 from last week lost.

The Giants stake their claim to the top spot after the last minute victory in Dallas Sunday night. Filling out the top five are two of the biggest movers of the week, with the Saints shooting up 12 spots to number 4, and the Jets, uh, jetting up 10 spots to round out the top 5. As for the biggest drop? That information has been blacked out by the NFL.

There is a bold, manly prediction buried in the rankings this week. Want to know what it is? Read on to find out!

Rank (LW)	Team	Record	Comments
1 (3)		2-0	There won't be a tougher road game this season than the one the Giants played on Sunday night to open up Jerry Jones' Ego Stadium.
2 (7)		2-0	With all the other contenders looking shaky, the Ravens have established themselves as the class of the AFC.
3 (5)		2-0	Time of possession. Total yards. Rushing yards. The Dolphins dominated the Colts on Monday night in every category except for the one that mattered: the final score.
4 (16)		2-0	They still haven't really beat anybody (Lions and a McNabb-less Eagles), but they aren't just winning games. They are destroying their opponents.
5 (15)		2-0	Whatever your team allegiance, you have to love the Jets talking smack in the media all week to the Patriots and then backing it up on the field.

6 (12)		2-0	For those of us waiting for a "prove it" game from the Falcons, here it comes: they get a desperate Patriots team this weekend.
7 (1)		1-1	That sound you hear is Jeff Reed in his garage with the car running.
8 (9)		2-0	After beating the Browns and the Lions, the Vikings get a real test this weekend with a visit to the upstart Niners.
9 (2)		1-1	I got my new dictionary today. I looked up overrated, and it just had the 2009 Pats team photo. Weird.
10 (6)		1-1	The offseason's trendy Super Bowl pick doesn't even have the best record in their division.
11 (4)		1-1	Blame their embarrassing loss against the Saints on McNabb's absence if you want, but last I checked he doesn't play defense. I think the loss of defensive coordinator Jim Johnson will turn out to be a bigger deal than anyone realized.
12 (17)		2-0	This team has won 8 games in a row dating back to last season, and is 8-2 under Mike Singletary.
13 (8)		1-1	How long until a Dallas player ends up on the injury report with a strained neck from staring up at that scoreboard?
14 (18)		1-1	I hope Jay Cutler remembers to send Jeff Reed a fruit basket.
15 (20)		2-0	This is as low as I could justify putting a team that hasn't lost a game yet.
16 (19)		1-1	A really clutch performance from Kurt Warner to keep his team's season from spiraling out of control before it even started. Have to respect it.
17 (23)		1-1	There's the offense we heard so much about! Unfortunately, that's also the defense we've heard so much about (Titans running back Chris Johnson had 281 total yards of offense on Sunday.)
18 (28)		1-1	The Bengals are one flukey Brandon Stokley touchdown away from a 2-0 start.
19 (10)		1-1	To everybody surprised they coughed up that game to the Bengals: remember, there is a reason this team went 6-10 last season.
20 (27)		1-1	Another team that's just one flukey play away from being 2-0, they put a hurting on an inept Buccaneers team.
21 (11)		0-2	Last year's 10-0 start is a distant memory. The defense that carried them last year was torched by the Texans.
22 (13)		1-1	So, uh, I might have gotten a bit carried away when I declared the race for the NFC West over after the Seahawks blanked the Rams in week one.
23 (21)		1-1	BOLD PREDICTION ALERT! BOLD PREDICTION ALERT! The Redskins will lose to the Lions this weekend. Consider yourself warned.
24 (24)		0-2	Jake Delhomme didn't throw an interception in this game! He also dressed himself and didn't poop in his pants. Congratulations, here's a cookie.
25 (30)		1-1	Was JaMarcus Russell the world's most predictable bust? I mean, was there ever even a question about whether or not he'd be a successful NFL quarterback?
26 (22)		0-2	Watching the Dolphins completely botch the two-minute drill on Monday night as they tried to come back to win the game, I thought: When did Andy Reid start coaching the Dolphins?
27 (24)		0-2	That game against the Raiders might have been the most unwatchable football game of all time.
28 (21)		0-2	Why did they get rid of Jeff Garcia again?
29 (29)		0-2	My strategy for my football knockout pool this season was to pick against Detroit whenever possible. However, I think this week I'm switching to the Browns (they are at the Ravens).
30 (31)		0-2	Meh.
31 (14)		0-2	If the people of Jacksonville can't be bothered with this team, why should I? (They were blacked out on Sunday because they failed to sell out.)
32 (32)		0-19	Don't worry, Lions. I don't think you'll be in this basement for much longer.
