From the vantage point of offensive coordinator Mike Shula, though, Manning has a familiar gleam in his eye.
"He looks good," Shula told reporters on Friday, via team transcript. "He's had a good week. He always has a good look in his eye. He's been great for me as a coach, to be around. I've learned a lot from him. I look forward to watching him on Monday night."
Manning hasn't quarterbacked the Giants to a victory since Week 14 of a season ago, bringing in an individual five-game losing streak as a starter. And, of course, he hasn't quarterbacked at all since September, though rust isn't a concern of his OC.
"Obviously, he's practiced every day," Shula said. "He's gotten himself ready mentally and physically. It's just a matter of getting back out there."
As for the play-calling, there shouldn't be much that changes -- other than one, huge glaring change with the younger, fleet-footed Jones out and the 38-year-old Manning in.
"We might not have him running the ball like we did with Daniel," Shula said. "But other than that, really nothing."
With Manning's return, however, a bit of nostalgia is in the air and perhaps the opportunity to pen a more fitting final chapter in Gotham.
