PHILADELPHIA (973espn.com) - Four years, four wide receivers coaches for Doug Pederson and the Philadelphia Eagles.

The latest attempt at creating some consistency at that spot on the coaching staff will come from within as Carson Walch has been promoted from assistant wide receivers coach to receivers coach, replacing Gunter Brewer, who spent just one year in South Philadelphia.

That's been a trend since Pederson took over the big chair for the 2016 season. Greg Lewis was one and done and the organization moved on to Mike Groh, who was promoted of offensive coordinator last season when Brewer arrived from the college ranks and North Carolina. The organization wasn't entirely happy with Brewer, who landed back in college at Lousiville and his assistant from last season will take over the day-to-day work at the position.

Before joining the Eagles in 2018, Walch spent the previous two seasons with the Edmonton Eskimos of the CFL and before that worked with Groh and Alson Jeffery in Chicago as an offensive quality control coach.

Three coaches from the 2018 staff —- Brewer, defensive line coach Chris Wilson and assistant offensive coach Eugene Chung —- will not be back for the 2019 season.

Roy Istvan was tabbed to help Jeff Stoutland on the offensive line while former training camp jack-of-all-trades G.J. Kinne has been added as an offensive assistant. On defense, former Dolphins defensive coordinator and longtime Jim Schwartz acolyte Matt Burke has been hired in an advisory role. A clearly defined defensive line coach has not yet been named but assistant DL coach Phillip Daniels could be in line for a promotion there.
