You probably haven't noticed, but Eli Manning has been one of the very best quarterbacks in the NFL over the past two seasons.
Manning's production fell to depths that few quarterbacks have ever managed to fall to back in 2013. A perfect storm saw him throw 27 interceptions while averaging below 7.0 yards per attempt and completing fewer than 58 percent of his passes. Manning was playing in an offense that required he hold the ball while executing deep drops in the pocket. The Giants didn't have the offensive line to hold up in those situations. He was in an offense that needed him to push the ball down the field to his wide receivers. Wide receivers who couldn't create separation downfield or win at the catch point. Manning couldn't rely on his running game or his defense, he did all he could do; He went down swinging.
Tom Coughlin never considered benching Manning. That may have been more about blind loyalty than incisive awareness but it was the right move. Manning wasn't the problem, he was just being dragged down by his situation.
