Every team is "predictable" to the masses if it doesn't crack out gimmick plays game after game. That's because the masses don't actually know what plays were called.
When it comes to critiquing playcalling, one can look to percentages, formations, personnel, etc.... The moment you start with the "predictable" argument without backing it up with explanations and details, you basically become useless in the discussion.
Brady calling his own number for QB sneaks is pretty damned predictable in short yardage plays when the opponent leaves the center uncovered, by the way. I don't hear too many people crying about that.
