The Philadelphia Eagles opened today's contest with an eye on roster shifts rather than on-field highlights . Retired veteran forward Jamie Cripps announced he will head back to country life after hanging up his cleats with the West Coast Eagles. On the offensive line, roster gaps have pushed several second-year players into larger roles, a topic coaches stressed during pre-game remarks. Training camp observers are tracking the tight end and fullback groups for early contributions. New line coach Chris Kuper is adapting Jeff Stoutland’s system, aiming the changes will improve protection. The Eagles will assess progress in the coming weeks.
