Ok, I'm finding all sorts of interesting info. Here's another list of all the games series by series.
MNF Series by Series
According to this list, the two most featured match ups on MNF are Broncos vs Raiders and Cowboys vs Redskins, with 14 games apiece. Also, GB has played more unique opponents on MNF than any other team, with 25 different opponents, the Vikings being our most frequent opponent at 5 games.
GB has had 18 home games, 33 away games, with a 25-25-1 record.
I found a place I can tally the home and away games for each team, but it'll take a quite a while. If I still can't find a site that lists them, and if I get ambitious tomorrow, I might do it.
