A lot of eyes are on how the Eagles' defense will evolve in Year 2 under the guidance of coordinator Bill Davis, but don't forget about changes on the offensive side of the football as well. Head coach Chip Kelly detailed how things will be different in 2014 during his Friday press conference ...

Chip Kelly: Riley Cooper in walking boot with foot injury, just cautionary, should be back in a few days. — Eagles Insider (@EaglesInsider) August 1, 2014

Kelly: Your offense always changes, always personnel-driven ... Identify the skill sets you have and tailor the offense towards that. — Eagles Insider (@EaglesInsider) August 1, 2014

Kelly on back shoulder throw: No different than running a slant or anything else, just another way to get the ball to the receivers. — Eagles Insider (@EaglesInsider) August 1, 2014

Kelly: Earl Wolff was a little sore yesterday, should be good to go yesterday. — Eagles Insider (@EaglesInsider) August 1, 2014

Kelly: Officials here did a great job yesterday meeting with position groups and explaining what they look for, what's emphasized. — Eagles Insider (@EaglesInsider) August 1, 2014

Kelly: We'll find out if special teams are improved during preseason games. — Eagles Insider (@EaglesInsider) August 1, 2014
