The Dallas Cowboys had four big coaching free agents as soon as their season ended on Sunday in Green Bay.
On Thursday, the club is expected to officially announce new contracts for head coach Jason Garrett, defensive coordinator Rod Marinelli and passing game coordinator/offensive play-caller Scott Linehan. The one coach not included in that group is offensive line coach/offensive coordinator Bill Callahan, who is expected to part ways with the Cowboys as several teams are lined up wanting to interview him this offseason.
Callahan has had a tumultuous time with the Cowboys. In 2013, he was enlisted as the offensive play-caller after Jason Garrett stepped away from the duty to focus on being a head coach. This past offseason, Garrett brought in Linehan to call plays even though Callahan kept the title of offensive coordinator.
In the meantime, the Cowboys blocked teams from talking to Callahan about offensive coordinator jobs since he technically still had that title with the Cowboys, even if it was basically stripped down to being an offensive line coach.
Make no mistake, Callahan is one of the league's most regarded offensive line coaches and helped produce the best line in the league in 2014, placing three of his offensive linemen in the Pro Bowl.
There are as many as eight teams interested in Callahan as an offensive coordinator, led by the Cleveland Browns, who were one of the teams who was blocked from talking to him at this time last year.
