All football tactics involve an element of luck -- something that's not worked earlier might work now. But for the Ravens, the three-man rush had been a disaster in the second half. Early in the third quarter, Pittsburgh had first-and-goal on the Baltimore 9, and the Ravens rushed three. The result was a touchdown pass to Heath Miller, who was open even though Baltimore had eight players dropping into coverage to cover five receivers in a small space. Late in the third quarter, Pittsburgh had third-and-6 on the Baltimore 8, and the Ravens again rushed three. The result was a touchdown strike to Hines Ward, again despite eight defenders covering five receivers. On third-and-10 with 3:25 remaining, the Ravens rushed three and allowed a 12-yard reception by Ward, though they had eight dropping into coverage to cover four on that snap. Then came the third-and-19 breakdown -- 58-yard reception by Antonio Brown, even though two safeties were lined up more than 20 yards off the ball at the snap.
