Reactions are pouring in across the league on the heels of the Eagles' contract extension of head coach Andy Reid through 2013.

Nobody knows how difficult it is to win consistently in the NFL like Charley Casserly, who has 24 years of experience as an NFL executive and 16 years as a general manager for the Washington Redskins and Houston Texans. Currently an NFL analyst for CBS Sports and the NFL Network, Casserly said that what Reid has accomplished during his tenure in Philadelphia is truly difficult to recreate.

"I think that Andy has done a phenomenal job there," Casserly said. "I think he's done a great job of hiring coaches through the years there, developing coaches. He has a great perspective on the big picture of what it takes to run a program. He certainly has done a good job of reloading with personnel. I think he has a great vision of what he wants the team to look like and he's done that.

In his first 10 seasons as head coach, Reid has led the Eagles to five NFC Championship games and is the winningest coach in both victories and winning percentage in Eagles' history. Since taking the Eagles from 5-11 to 11-5 in his second season on the job, Reid's teams have suffered only one losing season.

"It's hard, it really is, because you're going to have ups and downs," Casserly said. "I think that his consistency from game to game and year to year has been a real positive for the program in his approach. He's not a yo-yo; he's not up and down. It's hard to do that when you have the emotions of the team and the city, the up and down with injuries. So I think that's a great move by the Eagles."
