That's the crazy part, not only that they both won their division 8 out of 10 years, but the 2 years they didn't it was their turn to play our division anyways. I don't think non-division opponents have ever played each other this many consecutive years though I could be wrong
funny thing is that even if the patriots hadn't been scheduled to play the afc south in 2003 and 2009, they still would have played the colts because the colts finished 2nd in the afc south in 2002 and 2008.
