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 return to his roots after ending his career 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 immediate contributions. New line coach Chris Kuper is tweaking Jeff Stoutland’s system, hoping the changes will improve protection. The Eagles will assess progress in the upcoming weeks.
