(Photo by Ronald Martinez/Getty Images)The Dallas Cowboys officially moved on from offensive coordinator Scott Linehan this weekend, opening up a major hole on staff.According to the latest reports, the Cowboys could fill that vacancy internally by promoting quarterbacks coach Kellen Moore. A former Boise State star, Moore played for Dallas from 2015-17 before assuming QB coaching duties this year.If Moore is indeed promoted, the Cowboys could be looking at another one of their former signal callers to take over his old role. NFL Network’s Ian Rapoport has stated that Jon Kitna is a potential candidate for a staff position in Dallas.Kitna would take over for Moore as quarterbacks coach.I’m told “don’t laugh, this is a legitimate candidate” in Dallas https://t.co/hgt0onfroB— Jane Slater (@SlaterNFL) January 20, 2019Kitna played for the Cowboys from 2009-11 and then once again in 2013. Since 2012, he’s been a high school head coach at three different stops, most recently Brophy College Preparatory in Phoenix, Arizona.Kitna compiled a 36-16 record as a high school coach. Back in June, he was hired as the offensive coordinator of the San Diego Fleet of the new Alliance of American Football, which is set to begin play later this year.One has to think that if the Cowboys come calling, it will be tough for Kitna to turn that opportunity down.
