The Cowboys were reportedly unable to hire Jason Michael as their new tight ends coach. The Cardinals were able to seal the deal. A source told Sporting News on Tuesday that Michael will be joining the staff of new Arizona head coach Steve Wilks. He will replace Rick Christophel, who wasn't retained by Wilks. Michael, 39, had spent the previous two seasons as the Titans' quarterbacks coach after serving as their offensive coordinator in 2014 and 2015. He previously served as tight ends coach with the Chargers (2011-13), Titans (2008) and Jets (2007).
