They usually go with games that were close, even if they were shown on national TV, like last night's Atlanta-Chicago matchup. I don't mean to get off-track, but isn't it kind of pointless to re-show games that were on Sunday night or Monday night? I thought the point of NFL Replay was to show games that were very good but were only shown regionally, and people were griping they didn't get to see that game because they were stuck with their regional games.
Anyway, this weekend had a number of very close games, such as Minnesota-Baltimore, NYJ-Bills, and Atlanta-Chicago, so I doubt they would feature the Pats game. Plus I imagine they'll show NYG-Saints just because of the "battle of undefeateds, one of which was a Manning" factor.
