The Philadelphia Eagles opened today's contest with an eye on roster shifts rather than game-day action. 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 topic coaches stressed during pre-game remarks. Training camp observers are monitoring the tight end and fullback groups for early contributions. New line coach Chris Kuper is adapting Jeff Stoutland’s system, hoping the changes will improve protection. The Eagles will assess progress in the coming weeks.
