PHILADELPHIA -- Every Sunday, before most of the other Eagles had peeked out of the tunnel from the locker room, quarterback Matt Barkley stood in the middle of the field throwing passes.

At the other end: one of the Eagles' inactive receivers or tight ends. At Barkley's side: quarterbacks coach Bill Lazor.

According to ESPN's Ed Werder, Lazor is expected to leave Chip Kelly's staff after one season to become offensive coordinator of the Detroit Lions. Lazor would be charged with getting the most from quarterback Matthew Stafford, wide receiver Calvin Johnson and running back Reggie Bush.

The 41-year-old Lazor has the benefit of exposure to Kelly's innovative offense without being completely identified with a single system. Lazor came to the Eagles after three years as the offensive coordinator at Virginia. Before that, though, he worked for NFL head coaches Dan Reeves, Joe Gibbs and Mike Holmgren.

The Miami Dolphins reportedly interviewed Lazor for their offensive coordinator position. The Detroit situation seems like a better one. Instead of joining the staff of a head coach who could be on the hot seat in 2014, Lazor will be coming in with Caldwell from the beginning. And while Ryan Tannehill and Brian Hartline are a nice quarterback/wide receiver combo, Stafford and Johnson are among the most dangerous in the league.

In his one year with the Eagles, Lazor helped Nick Foles to one of the great individual seasons in history. Foles threw for 27 touchdowns and just two interceptions in 10 regular-season starts. His passer rating was a league-high 119.2.
