They complained for years that their receivers were touched by DBs but in this game the Pats got called (correctly) on an end zone call but the Colts got away with receiver contact when the ball was in the air and the receiver had position. That was a call that had serious implications on the outcome of the game which is not supposed to happen.
The other instance in that particular game when you had incidental contact or feet got tangled up are not things the refs are supposed to call.
While I never heard any complaints about two years ago and doubt that Dungy said much of anything about it I SAW what happened and complaints were justified.
