Running back LeSean McCoy was sporting a wrap around his injured right thumb at Sunday's training session, but said afterwards that it will be fine for the season opener against the Jacksonville Jaguars.

McCoy is coming off of a historic 2013 campaign - one in which he set the franchise record for yards rushing in a season with 1,607. The All-Pro is on pace to set the franchise's all-time rushing record this season. McCoy is thankful for head coach Chip Kelly, who has helped push and motivate him to be in the position that he's in.

"He just finds different ways to challenge me - on the field, about the game, in so many different ways," McCoy said. "That's why I like him as a coach ... a lot."

McCoy explained that he's learned about more than football from Kelly, who has shared life lessons that relate to fatherhood. One aspect of Kelly's ability to teach is how he conveys his messages.

"He never yells. That's another weird thing," McCoy said. "He doesn't really yell. He's always talking, teaching."

The NFL's rushing champion admitted that not only he, but all players need to be challenged. For McCoy, it's something different each year from just being in the NFL to becoming an elite back to taking the Eagles to the playoffs.

"He does challenge me. I'm a competitor. I like to compete," McCoy said. "That's the good thing about Coach Kelly. He's fair. He's honest and he likes the guys to compete."
