The Colts hate the Patriots. The Colts fans hate the Patriots, possibly more than any other fanbase in the NFL. The Colts fans also hate...well, pretty much everything to have ever come out of New England. For all I know, clam chowder is illegal in the city of Indianapolis.
But in spite of all this, the Colts and the Patriots are not rivals.
They used to be, that’s for sure; back when Peyton Manning was under center, the annual Indy vs. New England showdown was appointment television and were among the greatest games every played.
