Adding McCown gives the Eagles an experienced and talented quarterback in the room and his experience and perspective, along with a league-wide reputation as being one of the great locker room guys in the NFL, is a plus for the team. McCown will be on the field on Sunday when the Eagles resume practice at the NovaCare Complex, and he'll be deep in the playbook as he learns yet another offense playing with his 11th team in 17 NFL seasons.

McCown entered the NFL in 2002 and he's been part of a revolutionary era of offense at this level. He's long admired former Eagles head coach and current Kansas City head coach Andy Reid and has also has an extremely appreciative view of Pederson and his offensive scheme and play-calling abilities.

Learning the offense is something that McCown has done so many times it's almost second nature.

"I'm looking forward to it," he said. "I try to keep up with the league over the years and even in this offseason and you see the influences that Doug's had and who he's been around, it's cool. This offense performs at a high level. There is a lot to work with here and Doug takes full advantage of what he has here.

"In the 18 years that I've been around, to see where the NFL's offenses are now versus where they were when I started, it's neat. It's such a different game now. I'm a huge fan of what Doug does. A huge fan. I'm looking forward to seeing how Doug runs the team and how he oversees the offense. This is an ideal situation for me."

McCown served as the quarterbacks coach for his sons' high school team, so he's kept his arm in shape. As talks with the Eagles heated up during the week, he grabbed an NFL ball instead of tossing around a high school football and amped up his workouts. His sons were there for every throw and they've watched him throughout his career, and they both gave Pops the thumbs-up.
