Kevin Kolb has fond recollections of his time in Philadelphia, a turbulent period in which he was at different times the quarterback of the future and the quarterback of the past. On Sunday, he will start his first game against his former team. And Kolb said there's no bitterness directed toward to the other sideline.

"I learned so much there, highs and lows," Kolb said in a teleconference. "I have a lot of fond memories, actually. I think about it all the time. Even [the media], at times. I think the one thing it taught me was to not let the highs and the lows affect you that bad, because you never know when the next opportunity is going to be there. You never know how quick it can change. And that, obviously, is something you need to have to play in the NFL."

Kolb still keeps touch with many of the Eagles. He spoke to Jon Dorenbas last week.

Kolb speaks with a unique perspective on the franchise and the city. Two players on the current roster whose situations he can especially understand are Nick Foles and Michael Vick. Kolb was once the rookie quarterback pushing an established veteran. He's also been a starter whose job has been in question.

"It's probably good for Nick to feel [pressure] early on just to understand there's no time to take off," Kolb said. "And also to see what Mike has to go through as a starter, because we've been there. We've watched Donovan go through that."

After Kolb took the starting job when Donovan McNabb was traded, he lost his starting job to Vick. In Arizona, he lost his starting job to John Skelton. So Kolb can understand what it's like having a backup who is a favorite of fans.

"For Mike, it's going to push Mike to go harder than he is," Kolb said. "I've heard some of his comments on TV. Knowing him well, I know bad he wants it. I know he bad he wants to play perfect. There's a balance there between trying hard and cutting it loose as well."
