It happened.
The Dallas Cowboys officially decided to move on from Mike McCarthy following his five seasons with the team, it was reported as a situation where a deal could not be reached, and whether or not you think that was the right move, the move has been made.
With the McCarthy domino having fallen the Cowboys are now going to be tasked with finding a new head coach, the 10th one in franchise history and the 9th to work for the team in the ownership era of Jerry Jones. Obviously only Tom Landry did not.
