Given the composition of the Philadelphia Eagles team he has inherited from Andy Reid's staff, new coach Chip Kelly still hasn't moved or revealed plans to address the two biggest question marks about his team heading into 2013: quarterback and defensive coordinator. Everyone knows by now that Michael Vick definitely will not be retained at the salary he's due to make and is not likely to return regardless of whether he'd be willing to take less, which he still is not reportedly ready to do. That leaves Nick Foles, who showed enormous promise despite an uneven rookie season in which the only win he led the team to came on the last play of a game at Tampa Bay, where the fading Bucs showed very little life. The recent revelation that San Francisco 49ers veteran Alex Smith will seek his release before the NFL's free agency period begins in March could impact what they do here. After an uneven start to his own career, in which many were obviously way too quick to label him a bust, Smith has proved over the last two seasons, in which Jim Harbaugh has stabilized the whole football operation, that he could operate a championship contender at a high level.
