Why do the Philadelphia Eagles seem to always be in playoff contention? Largely because they excel at locking up their young players before they reach free agency, consequently keeping their foundation intact.

They stuck to that formula Thursday, extending all-pro RB LeSean McCoy's contract though the 2017 season.

"We are excited to continue this offseason of taking care of our own players," head coach Andy Reid said in a statement. "LeSean is one of the most electrifying running backs in the National Football League. He can do it all -- run, catch, block and score touchdowns from anywhere on the field. He's worked extremely hard to turn himself into a Pro Bowl running back and he is well deserving of this contract extension."

Philadelphia previously extended WR DeSean Jackson, DE Trent Cole, T Todd Herremans and G Evan Mathis this offseason.

McCoy set Eagles records in 2011 with 17 rushing TDs (a figure that also topped the NFL) and 20 total scores. He rushed for a career-best 1,309 yards as well, burnishing his reputation as an all-around back. McCoy has averaged 1,648 yards from scrimmage over the past two years and totaled 126 catches in that span.

Per PFT, his five-year extension maxes out at $45 million with $20.8 million guaranteed.

Happy Mothers Day indeed, LeSean.
