After a loss to the Ravens in which Caleb Sturgis missed a last-second 57-yard field goal that would have tied the game, the Dolphins noticed that Baltimore pulled the same maneuver the Patriots got busted for yesterday. Miami sent video of the play to the league and the league reportedly admitted that the call should have been made.
According to a couple of sources who spoke to Albert Breer, once Miami made the league aware of the play, the Dolphins were told the rule would become a point of emphasis around the league. Of particular interest is that the NFL's VP of officiating, Dean Blandino, sent around a training video about the play, noting officials would be looking out for it.
The very next week, the Pats got away with it against the Saints. One week later, they got greedy.
