Most tellingly, Manning called it “Coach McAdoo’s offense.” The schemes will not emanate in the office of Coach Tom Coughlin, an offense-minded coach since the 1970s. It is also not Manning’s offense; he said he had no input so far.

It is a Giants leap of faith. But so far, the players seem energized by it.

“I think it will be good for all of us,” said Rueben Randle, who is projected as the No. 2 wide receiver, behind Victor Cruz, now that Hakeem Nicks has joined the Indianapolis Colts as a free agent. “It will cut down on the mistakes in communication.”

Randle was frequently at the heart of the disconnect with Manning in 2013. The offense run by the longtime coordinator Kevin Gilbride relied on nuance and nonverbal interplay between Manning and the receivers, who often talked about learning to “see what Eli sees,” as well as thinking in tandem with the quarterback.

The approach produced two Super Bowl victories. It also contributed significantly to Manning’s career-high 27 interceptions last year. But McAdoo is not planning to rely on cosmic communication between Manning and his receivers.

“Your route is your route,” Cruz said. “You can dictate that off the coverage and you know what you have, and Eli can find you within different holes in the secondary.

“But it’s a lot less dependent on what my body language is and Eli reading that,” he added. “It’s more about him reading the coverage and finding me in those open holes.”

Players did not describe the system as simpler but said it was perhaps easier to operate and faster-paced. The Packers were a common reference point.
