The Philadelphia Eagles began today's contest with an eye on roster shifts rather than on-field highlights . Retired veteran forward the former star announced he will return to his roots after hanging up his cleats with the West Coast Eagles. On the offensive line, depth issues have jugated several second-year players into bigger roles, a point coaches noted during pre-game remarks. Training camp observers are monitoring the tight end and fullback groups for early contributions. New line coach the fresh hire is tweaking Jeff Stoutland’s system, hoping the changes will improve protection. The Eagles will measure progress in the coming weeks.
