Felix Jones heard the catcalls and saw the inspired fans whenever the Dallas Cowboys played the Eagles in Philadelphia.

That’s why the running back said “it’s a little weird” to switch sides and play for the Eagles, which he did Tuesday by signing a one-year contract.

“It’s a great rivalry,” Jones said. “It’s good-natured fun. I’ve been loving (the rivalry) since I was a little boy. I’m excited to be on the team. They have great players, great coaches and I’m thrilled to be here.”

Jones was the Cowboys’ first-round draft choice (22nd overall) in 2008. But he never developed into that star running back the Cowboys were hoping for since Emmitt Smith left after the 2002 season.

Jones rushed for 2,728 yards in five seasons, but the Cowboys let him become a free agent in March. Jones said teams weren’t lining up to sign him, either.

“Well, obviously, none,” he said when asked if he had other offers in March.

Jones worked out for the Eagles and the New England Patriots last week. The Cincinnati Bengals were reportedly interested as well.

Jones decided on the Eagles, even though he might end up as the third running back if he makes the team, behind LeSean McCoy and Bryce Brown. He said the uptempo offense of new coach Chip Kelly convinced him that there could be plenty of carries to go around.

“Once I visited the Eagles, and I got to know their coaches and figured out their system, and how things would be going, I kind of liked it,” Jones said. “I felt like it fit me.”
