I know you were trying to keep everything out of conference, but it'd make more sense IMO to pair Denver with New England and Green Bay with Seattle. GB/Seattle would have been much greater 3 years ago, when Green Bay was starting Seattle's former RB, while Seattle was starting GB's former backup QB and was led by GB's superbowl-winning coach, back in the "We'll take the ball... and we're going to score!" days... but Seattle's such a bland team, there's really no better option to pair them with outside of Pittsburgh (who is already taken). The Holmgren/Green/Hasselbeck/"We're going to score" link will have to suffice.As for Denver/New England... it practically *WAS* a rivalry game for a long time- Between 1995 and 2006, Denver and New England played each other every year except for 2004. Of course, they made up for it by playing New England twice in 2005. Lots of history between the two teams- you have Elway owning New England throughout his entire career, Shannon Sharpe calling the national guard, Bill Belichick taking an intentional safety, Champ Bailey running an INT back 100+ yards and NOT scoring, Denver ending Brady's perfect postseason streak, etc. As a Broncos fan, I'd love to see that come back and become a yearly thing.The NFL's current schedule set up is soon going to finish it's 4 year rotation for the 2nd time, after which the NFL is set to reevaluate it. With discussion already out there of adding a 17th game, let's say hypothetically that they add the game and decide it will be a rivalry game that recurs every year (regardless of whether the teams would have played that year because of the rest of the schedule or not).Lets assume the rivalry cannot be with a team already in their division. While it's possible they would restrict rivalry games to being out of conference, let's not make that a requirement here. So the game can be any team in either conference, so long as they aren't in the same division. No division realignment will take place.What do you think the matchups should be?While I said they don't have to be out of conference, I believe all the matchups I came up with were out of conference. I like most of them, though a few (Pats-Packers, Bengals-Falcons, and Bills-Vikings) were more about pairing up the teams who were left.Bills - VikingsDolphins - Bucs Pats - PackersJets - Giants ...
