Luckily for Nassib, Manning appears comfortable teaching the young quarterback everything he needs to know about winning as the starting quarterback of the Giants.
According to the New York Daily News' Stephen Lorenzo and Ralph Vacchiano, Manning called Nassib shortly after the Giants picked the young signal-caller and offered his help:
(I told him) 'Anything you need before you get here in May, let me know. Looking forward to working and getting to know you. We get after it in the quarterback room. We work hard. We have great meetings. Looking forward to having you involved in this.'
There's little question that Nassib's first lesson from Manning will come in the quarterback meeting room.
The NFL is a tough business both on and off the field, especially at the game's most important position. The great quarterbacks in the league are not only physically gifted—like Nassib—but also mentally prepared for any situation thrown at them.
Such preparation comes from tireless work in meetings and film rooms, and is quite possibly the biggest hurdle for young quarterbacks to master.
A quarterback needs to know the playbook inside and out, but also how to run through his progressions in an instant, make pre-snap reads of exotic defensive coverages and shift protections to keep 270-pound pass-rushers out of his pocket.
These requirements force the NFL to throw a lot of information at young players in a short amount of time. It can overwhelm and swallow still-adjusting players who can't handle it.
Manning, a veteran of the process, will certainly provide a successful role model for Nassib early in his career.
Expect Manning to also show Nassib how to act in the bright lights of the New York media.
Even as a backup quarterback, Nassib's every move is going to be under the microscope in the Big Apple (just ask that Tebow guy). The same goes for Manning, yet he's kept a mostly clean reputation because he knows how to handle the spotlight. Eventually, if Nassib wants to be a starting quarterback in New York, he'll have to be able to do the same.
If Manning can't provide guidance in that area, can anyone?
But above all, Manning can provide championship insight to a young quarterback. Manning has won two Super Bowls and there's very little he hasn't seen or dealt with during his time in New York. He knows how to win and play big in the most important moments.
Nassib should be able to pick Manning's brain for any bit of help he needs as he transitions from the Big East to the NFC East.
The Giants will hope having a tutor like Manning will pay off. Eventually.
Manning is still an elite quarterback, and at just 32 years old, he should have several good years left in the tank.
Drafting Nassib was a smart long-term decision, for no other reason than it gives the Giants a malleable quarterback with obvious physical skills behind Manning.
There's no rush for him to play or threaten to play. This is Manning's team, Manning's town.
However, Manning can also provide a learning platform for down the road when Nassib is ready to challenge for his playing time. That day will eventually come and Manning didn't shy away from that fact.
“I feel like I’m playing at a high level. This is the prime of my career,” Manning told the New York Daily News.
"I understand that one day it will end. In this league you never know when that day comes.”
When that day comes, the Giants should have a ready-to-play option in Nassib.
