Eli Manning dropped back and watched Victor Cruz working against a single cornerback on an empty football field. Manning delivered a throw in rhythm. And then he did it again, as another receiver worked one-on-one against another corner.

And again. And again. And again.

It’s a simple one-on-one drill that performed regularly in training camps. But this is what it’s come down to for the Giants’ struggling aerial attack. On Tuesday, coach Tom Coughlin met with Manning to discuss the team’s recent offensive doldrums. And then on Wednesday, midway through the regular season, the Giants took a mid-practice break from their preparations for Sunday’s game against the Bengals to work through a training camp drill.
