Reporters will come on Sport Talk radio and tell these stories, but they generally won't put it in print. The Cowboys media guys like Broaddus, Mickey, etc. will tell some of these stories on their video shows (The Break, Talking Cowboys) but generally won't put it in print. Also, I know one of the local media guys that covers the Cowboys and they all know a lot of stories that don't get reported. Local media have to be careful about what they report because team officials can cut off their access to the team in terms of interviewing players, etc.
I think it is generally well know that Callahan departed because he did not get along with Garrett. Callahan was able to go directly to Jerry on issues and bypass Garrett. That's how Callahan ended up as the O-Coordinator for a year. He convinced Jerry that he could do it better than Garrett. If you remember, Garrett would not admit all that off-season that Callahan was going to call the plays, but the media all seemed to know it was going to happen based on their questions and it did indeed happen. There a was a lot of discussion about how Callahan would call the plays but they would stay with Garrett's scheme. Anyway, that was the major part of their rift but they had already had issues before that which included Callahan wanting to bench Free with Garrett refusing. Callahan appealed to Jerry and they compromised with Free and Parnell splitting snaps in the final 4 games that season. The next season Parnell was injured in training camp and Callahan became the OC. Calllahan was replaced by Linehan in 2014. Garrett didn't want Callahan to call the plays but Jerry didn't want Garrett to go back to calling plays so they brought in Linehan in 2014. Callahan wanted to leave then, but was under contract and Jerry insisted that he stay. When Callahan's contract was up after 2014, he departed for the Skins.
