This isn't just an NFL thing... I've seen it in other sports (like NCAAB) where teams play certain teams twice in the same season.
But is it THAT hard to schedule such that you don't play the same damn team two weeks apart?
Cincy & Baltimore played last night. They play again on Dec 14.
How does that make sense? Shouldn't they try to separate those type of divisional matchups maybe 5-6 weeks at minimum? Mostly play divisional (2-play) games early in the season, late in the season, and fit the 1-play teams in between?
