The Colts, coming off a tough loss to their nemesis, now get to play a team that the actual players don't have that much animosity towards, but the fans shutter at the prospect of, the Saints.
When it comes to Colts opponents, the Patriots are in another stratosphere from everyone else. The Colts play them every year, almost always lose, and the Colts can never seem to get a leg up on them, no matter the circumstances. Usually division rivals you grow to hate, just because of the familiarity of the teams, but when your favorite team has won the division in 10 of the 13 years it existed, you don't get that natural instinct to dislike a team.
