Appalachian State head coach Scott Satterfield has announced that Dwayne Ledford, who is in his second year as App State University’s offensive line coach, and Frank Ponce, a longtime assistant at Florida International University, will serve as the Moutaineers’ co-offensive coordinators. … Oregon head coach Mark Helfrich has hired former Arizona Cardinals defensive line coach Ron Aiken to coach the same position for the Ducks. Aiken replaces Jerry Azzinaro, who left Oregon to join former Ducks coach Chip Kelly with the Philadelphia Eagles. Aiken spent the past six seasons with the Cardinals. He coached the defensive line at Iowa for eight season (1999-2006) and spent one year as linebackers coach at San Diego State in 1998. Aiken also had stints as a defensive assistant at Texas (1997), Vanderbilt (1995-96), and New Mexico (1991-94). … Also at Oregon, Helfrich has officially announced Scott Frost offensive coordinator and quarterbacks coach. This has been speculated since Helfrich was hired, but Helfrich waited until after Duke’s Matt Lubick was hired as wide receivers coach and passing game coordinator (which happened on Monday) to make the announcement. Frost, the former Nebraska quarterback, has served as the Ducks wide receivers coach since 2009. Frost broke into coaching as a graduate assistant at Nebraska in 2002 before filling the same role at Kansas State in 2006. He then spent two years Northern Iowa in 2007 before joining the Oregon staff.
