The Cowboys released running backs coach Skip Peete and defensive coordinator Rob Ryan last week, and there could be more changes to the coaching staff on the way.

During an interview on dallascowboys.com, team owner/general manager Jerry Jones said he spent extensive time with coach Jason Garrett evaluating the coaching staff.

"We spend a certain amount of time between now and training camp," Jones said. "We have spent time, ad nauseam, certainly you spent that kind of time from a management standpoint. You spend that type of time with your coach and your coaches, anytime you might be looking at staff changes and you have to spend a lot of time with your head coach regarding that for sure."

The next step for the Cowboys is trying to figure out which defensive coaches will remain with the Cowboys. There were reports Friday night that Rob Ryan would become a defensive coordinator with the St. Louis Rams.

Ryan told ESPNDallas that wasn't the case.

"I'm on a beach and have talked to nobody and have no comment," he said.

If Ryan does leave, it's expected he would bring some of the defensive staff with him to St. Louis. That could include linebackers coach Matt Eberflus and maybe secondary coach Jerome Henderson.

The Cowboys have told defensive coaches they may interview for other positions despite having years left on their contracts.

The Cowboys also have to hire a running backs coach, and other changes may take place regarding the duties of some of the current coaches, including Garrett.
