There’s mutual interest between the Cowboys and backup quarterback Josh McCown, according to Ed Werder of ESPN.com (on Twitter). However, the Tony Romo situation has to play out first. Werder adds that the Cowboys’ desire to add McCown could be a factor in the timing of the call on Romo. 
Of course, Romo currently stands as the No. 2 quarterback on the Cowboys’ depth chart, but the veteran is pushing for an opportunity to start elsewhere. It is believed that Romo would like to be granted an outright release while the Cowboys, presumably, would like to get something for him via trade. If Romo is cut loose, he will have total freedom to choose his next team. In that event, some have speculated that the Cowboys and Romo could make a tacit agreement in which Romo does not sign with a specific list of rival clubs.
McCown, 38 in July, is listed as one of my top 15 quarterbacks available this offseason. He’s obviously no longer a starting caliber QB, but he could serve as an experienced Plan B behind star Dak Prescott. For his part, McCown says he has heard from four or five interested teams.
