Technically, that's true, but considering it's the Pats, I think it's pretty safe to project that Chip's team won't be as good. I mean Pats will beat you guys with Jimmy G under center. And the fact that game is later in the season is actually a problem for Philly - Pats are one of the few teams who get better and better as the season progresses; you want to beat them, have to catch them early while they are still coming together as a team.
Even with BB and Tommy set aside, Pats have one big up on Philly by default - Pats are a team built thru the draft, Philly is a collection of players put together via free agency, with a revolving door as a team mascot and rather shaky structure (at least right now). As I said, Pats will hang a 40+ on your Chipster with the back up QB and Tommy on the bench, looking at naked pics of Giselle.
