One of the reason Eagles fans seem to be so excited about quarterback Nick Foles is that his apparent arrival as a star in the league signifies the end of team's search for a franchise quarterback.

Speaking on FOX Sports 1, the team's last franchise quarterback warned Foles not to expect the love to last too long.

"Just be ready for the boos," said former Eagles quarterback Donovan McNabb.

Being booed during his time in Philadelphia is obviously something that has stuck with McNabb, who is arguably the best quarterback to ever play for the team. McNabb was famously booed when the Eagles selected him with the No. 2 overall pick in the 1999 NFL Draft, and ended his tenure with the team on a bad note in 2009.

A big reason fans never fully latched on to McNabb was his inability to win a Super Bowl, an expectation the fan base had after the team reached five NFC Championship games.

The expectations for Foles this season are not as high, but McNabb said he is worried about the fans turning on the young quarterback if he can't produce like he did last season.

“I’m just a little worried if he can do it for a full season,” McNabb said. “I’m just worried about that aspect, not so much of his health, but can you be consistent like what we saw last year? We’ve seen so many quarterbacks give us one year of greatness, and then all of a sudden they can’t live up to the expectations. I’m not saying he can’t do that in that offense, but I think expectations are a little bit too high for Nick Foles."
