Why do the Colts seem to get a gift p interference call whenever they are losing?

There is no team in the nfl that gets more beneficiary bad calls to help them win than the Colts. I told my friend before the game if the Colts get down the refs will give them a gift bs p interference call to set up a score and sure enough. You see it everytime the Colts are in a big game they always get these rediculous calls. I challenge anybody to tell me a team that consistently gets more bad calls go their way.
