There is a term in European football—commonly known as soccer in the U.S.—that describes an opponent that, regardless of circumstances, a team always has trouble overcoming. This bogey team, as they are called, is usually an underdog that time and again pulls a shocking upset over a heavily favored powerhouse, but the term can apply to teams on equal footing or the opposite as well.
For the Indianapolis Colts, the closest thing they have to a bogey team is the New England Patriots. Since the calendar turned to 2010, the Colts are 0-6 against their AFC rivals and 0-2 in the playoffs.
