At this point it’s not a big secret: the Philadelphia Eagles’ offensive line has some questions that need answering, specifically at the guard position. The departures of Evan Mathis and Todd Herremans left two holes that, on paper, appear to be filled with lesser players in Allen Barbre and Matt Tobin. John Moffitt was a shrewd signing by the team to provide depth for one of those positions, but the Eagles could get even slicker and pull a trade for Zane Beadles during training camp.
