But teams with young franchise quarterbacks often like to lock them up, as the San Francisco 49ers did last week when they gave Colin Kaepernick a complicated six-year, $126 million deal that includes as much as $61 million guaranteed.
"You get a contract like that because you play well and you show them you can be that guy for the franchise," Foles said. "I have to continue to prove that, each and every day. . . . When I'm playing out there, there's no dollar sign on me when I throw a ball."
Foles said he was "happy" for Kaepernick, whom Foles has followed since college. Foles did not put much thought into Kaepernick's setting the market, which will be tested in the coming months with Carolina's Cam Newton already eligible for an extension, and Indianapolis' Andrew Luck, Washington's Robert Griffin III, and Seattle's Russell Wilson able to negotiate their second contracts after the 2014 season.
"I've always said that how I play, how our team is, how I am as a leader will all take care of [the contract] when the time comes," Foles said. "I'm really just having fun out here. I'm having fun with my teammates."
Asked whether he pays attention to the deals from a business perspective, Foles said he does not.
In his first spring as the unquestioned starter, Foles has worked on moving more efficiently in the pocket, improving his downfield throwing, and understanding the different checks in the offense. He also has made it a priority to help younger players.
When second-round pick Jordan Matthews was asked for his impression of Foles, Matthews immediately said "leader." Foles is now one of the team's top players, and he takes his leadership responsibilities seriously. That's all part of the package the team looks for when determining whether to make a long-term investment in a quarterback.
When Lurie became an owner, he kept a bedside list of ingredients he believed were necessary for a winning franchise. One of them was a franchise quarterback. In Lurie's 20 years as owner, he has not been hesitant to pay top dollar to quarterbacks who fit that description. Donovan McNabb and Michael Vick both received big contracts from the Eagles.
Foles might be next in line. He needs a strong 2014 campaign to help his case. He laughed when asked whether the contract came up in the post-practice conversation with his boss.
"No, he's just a good dude; we were talking about practice," Foles said. "That will all take care of itself later."
