Colts vs. Chargers, Jags vs. Pats

So, if you haven't noticed, there is a lot of talk about how the Cowboys and Patriots will lose this weekend. I'm not making any predictions yet, Coin Toss section to come on both games, but it seems to me like the Colts are once again being ignored. All season long everyone picked the Colts over the Patriots in most power rankings because they were the defending champs. When the Pats finally beat them, people changed. But it seems like things have gone back. I just think people don't know how to handle a team as perfect as the Pats have been (I saw the Eagles and Ravens games, so don't yell at me about those). Columnists seem to be constantly expecting an upset so it's like that they're such a sure thing that they've become the underdog. On a quick balance of positions, it's difficult to see the Colts as having a much easier game ahead of them than the Pats do. For instance:

Jags vs. Bolts
QB: David Garrard vs. Phillip Rivers
RB: LaDainian Tomlinson vs. Maurice Drew-Jones/Fred Taylor
WR: Chris Chambers vs. Reggie Williams
TE: Antonio Gates vs. Marcedes Lewis
CB: Antonio Cromartie vs. Rashean Mathis
FS: Marlon McCree vs. Reggie Nelson
C: Nick Hardwick vs. Brad Meester
LT: Marcus McNeil vs. Khalif Barnes
DT: Jamaal Williams vs. Marcus Stroud/John Henderson
MLB: Brandon Siler vs. Mike Peterson
OLB: Shaun Merriman vs. Daryl Smith

I mean, it's not often a huge difference, but I'd give advantage to the Chargers. And between the Pats and Colts, although it's close, wouldn't you say the Chargers have at least a slightly easier game? It just seems to me that because Peyton Manning won a Super Bowl, he's now invincible. But since Tom Brady won four, and went 16 - 0 this regular season, he's ripe for an upset? Makes no sense to me. The man who doesn't seem to often lose seems like the sure bet... at least compared to the guy whose Number 1 Receiver has not been seen alive since Week 10. For all we know, they had to amputate Marvin Harrison's legs, graft them onto Craphonso Thorpe... and for good measure put the hands on too.
