How about the Falcon's Offensive Coordinator Mike Mularkey? The Falcons are having a pretty good season which is a shocker. This guy has HC experience too. I know, this is unlikely as well. Here is some info about him however.
Mike Mularkey comes to the Falcons with a vast amount of coaching and playing experience in the NFL, which includes two years as a Head Coach (Buffalo Bills) and two stints as an Offensive Coordinator — one with the Pittsburgh Steelers (2001–2003), and the other with the Miami Dolphins (2006). He also forged a successfull playing career that spanned nine years in the League as a tight end for the Minnesota Vikings (1983–1988) and Pittsburgh Steelers (1989–1991).
“I’m really excited to have Mike join our staff,” said Falcons Head Coach Mike Smith on the hiring of Mularkey. “He is a well respected coach in this League who has had success for many years at a high level as an Offensive Coordinator and Head Coach.
