I think the H2H doesn't matter so much because a) its still a relatively small sample size (i.e. these two teams don't play each other twice a year) and b) you get different roster constructions throughout.
I honestly didn't think Andy Reid was particularly good yesterday either. I think their offense was good for about a quarter to a quarter and a half, but I saw nothing special from Reid in the second half or even in the later part of the first half. They basically just took check downs all game, and couldn't beat man coverage in the second half.
I think MM and Spagnuolo both had great days, and I think Reid and Monken didn't. And it came down to which QB/team made the bigger mistakes. And we did.
