Three teams in 13 days. Three coaches, three systems, three cities.
 
“It’s been a whirlwind couple weeks,” Aaron Murray said. “But it’s nice to be here.
 
“In this business, you have to be ready for anything. You just never know where you may end up or what situation you’re going to be in.”
 
Murray, who holds SEC records for career passing yards and touchdown passes, signed to the Eagles’ practice squad Tuesday after being released by the Cardinals, who signed him to their practice squad Sept. 6 after the Chiefs cut him on Sept. 2.
 
“I got released and literally left the airport in Atlanta, got home, sat down to eat dinner and got a call from Philly,” Murray said. “They told me I had a flight in a few hours. My bags were still by the front door.”
 
Normally, practice squad additions aren't big news, but since the Eagles only have two active quarterbacks, Murray becomes potentially a key guy.
 
His offensive coordinator the last two years? Doug Pederson. His teammate the last two years? Chase Daniel.
 
“I think automatically, he comes in and knows the offense right away,” Daniel said. “That’s a huge, huge help, not only for him, but for Carson as well, because he has another guy in his ear that can tell him, ‘Hey, maybe look at this one a little different.’ He’s already doing it.
 
“It’s a group thing now, and I think three brings a whole new dyamic to the table, which is good. As many eyes as possible. That’s what you want.”
 
With Pederson, Daniel and Murray, the Eagles now have three key figures from the Chiefs’ quarterback room of the last two years. All that’s missing is Alex Smith.
 
“It’s awesome,” Murray said. “You get here and open up the playbook and you pretty much know the meaning of everything. There are some things Doug changed with protections and formations, so you still have to get in the playbook every day and study.
 
“When I got to Arizona, it was all new concepts and a completely different way of calling things. You come here and I’ve only been out of this system for about a week, so it’s pretty fresh in my mind and I’m very comfortable with it.”
 
Murray, only 25, was very good in college — 121 touchdowns, 41 interceptions and plenty of school and conference records playing for Georgia.
 
So you never know what the future holds. But for now, his role is holding the clipboard, running scout team in practice and sharing his knowledge of Pederson’s offense whenever he’s asked.
 
“He's a kid that knows our system … so he knows a lot of things that we're doing,” Pederson said. “And he’s solid. Good kid, good athlete (and) can make all the throws.
 
“He's much like Chase in the sense that he's going to help where he can. Be another coach out there on the football field and I’m excited to have him with us.”
 
Murray was the Chiefs’ fifth-round pick in 2014 out of Georgia, where he was a four-year starter.
 
He never played a snap in Kansas City, never got into a game.
 
“It’s tough,” he said. “Everyone is a competitor, and if you’re not a competitor you don’t belong in the NFL. You want to be out there and compete and help your team, so when the season comes, you have to figure out what your role is, find your role and execute it, whether it’s help Carson and Chase breaking down film, giving some advice here and there or whatever I can do to help.”
 
The Eagles have been forced to use their third quarterback for meaningful snaps a number of times over the years.
 
There was Brad Goebel, Jeff Kemp and Pat Ryan in 1991, Ken O’Brien in 1993, Mark Rypien in 1996, Bobby Hoying in 1997, Koy Detmer in 1998, 1999 and 2005, A.J. Feeley in 2001, 2002 and 2006, Mike Kafka in 2011 and Matt Barkley in 2013.
 
It does happen, and right now that guy is Murray.
 
“I think Aaron is a great young quarterback,” Daniel said. “I think his familiarity with the system and Doug is what got him here, but he can play. He can sling it around the park a little bit.
 
“I know I’m excited to have him here. He can just jump right in and roll.”
