PHOENIX - Eli Manning and Jason Pierre-Paul are two of the most decorated players on the Giants' roster, but they could be facing "prove it" seasons in 2015.

Neither is under contract with the team beyond then -- Manning is in the last year of the extension he signed before the 2010 season and the Giants have placed a franchise tag on Pierre-Paul -- and there seems to be little momentum to get long-term deals done at this point in the process.

The Giants do seem to be more focused and optimistic about reaching an agreement with Manning. There is no timetable to get something done with the franchise quarterback, but neither of the team's two top-ranking officers is keen on going into the upcoming season with Manning as a lame-duck quarterback.

"Ideally, we'll get something done," Giants president and CEO John Mara said at the NFL owners' annual spring meetings Monday. "Whether it happens or not, I don't know."

Steve Tisch, the team's chairman and executive vice president, said he is hopeful that Manning will be "a Giant for life."

Manning has been named Super Bowl MVP twice for the Giants, but the team has not made the playoffs in five of the last six seasons. And Manning is 34 years old, all of which must be considered by the Giants before committing to him.

"I think there's a lot of great quarterback left in Eli Manning," Tisch said. "He's had a couple of off years. The team has had a couple of off years."

Tisch insisted there is no rush to work out a contract extension with Manning.

"There's no guns to anybody's head, there's no ticking clock," he said. "At the same time, no one is going to be complacent and take anything for granted because he's got very sophisticated representation. But I'm very optimistic we're going to do something."

As for Pierre-Paul, Tisch is less certain about his future with the Giants. They applied the franchise tag to keep Pierre-Paul off the free-agent market, but they still want to see him play a full season the way he finished 2014. He was slowed in 2013 and the start of 2014 as he recovered from back surgery.

"I'm a big JPP fan," Tisch said. "I think a lot depends on how he performs this season. He's going to come back in great shape physically, mentally. So if he's a key to the team's success this season, I think we're open to [a long-term deal]."
