It was a first-time meeting in the weight room this week between Philadelphia Eagles 3-day rookie offensive linemen Trevor Keegan and Dylan McMahon, and retired Eagles legend Jason Kelce, writes John McMullen for Sports Illustrated.

The six-time All-Pro center and future Hall of Famer made an impression when he stopped by., according to Eagles GM Howie Roseman.

The connection between McMahon and Kelce was particularly interesting.

Kelce came into the NFL as an athletic sixth-round undersized longshot in 2011.

Now McMahon as arrived as the athletic-undersized pivot hopeful from North Carolina State. He was selected as No. 190 overall, one slot ahead of where Kelce was 13 ears earlier.

“That was a pretty crazy moment because I’ve watched him since I was little playing football,” McMahon said of the meeting.  “[Kelce] looked at me and said, ‘Undersized center?’ ”

“We have that in common.”

McMahon is appreciative that Kelce is around to be able to “pick his brain once in a while”.

“It was pretty surreal meeting him and he just said he hopes to be able to help me out in any way he can,” the rookie said. “It was pretty cool.”
