Talk that new coach Chip Kelly’s fast-paced offense could run into trouble with officials who can’t keep up is being disputed by an NFL official who worked an Eagles practice. NFL official Scott Green was at Eagles training camp this week and said he doesn’t see any reason the league’s officials will have any problems with spotting the ball quickly enough to keep up with the pace the Eagles’ offense is running. Green said no issues arose during the portion of practice when the Eagles went 11-on-11 with a live clock.
