The Cowboys are working on contract extensions for offensive coordinator Scott Linehan and defensive coordinator Rod Marinelli.

"Without getting into specifics, I want to use the words very good," Jerry Jones said of the negotiations. "We are not ready to do any announcing, but it's all good."

Linehan and Marinelli signed three-year deals in January 2015 that paid each around $2 million annually.

Linehan has been the Cowboys' OC since 2014. Marinelli was hired to coach the defensive line in 2013 before being elevated to defensive coordinator in 2014.

Marinelli discussed the importance of Dallas' coaching staff continuity after a Pro Bowl practice last month.

"I think it's really important," Marinelli said. "It goes back to coach [Tony] Dungy for me. We kept our staff together until they got better jobs. You find teachers. Teachers are hard to find, that really want to teach the game. I think once you get really good teachers, and you keep working, then you got something special."

What kind of teachers do the Cowboys have?

"It's special," Marinelli said.

: The current plan is for the Cowboys to open training camp in Oxnard, Calif., travel to Canton, Ohio for the Hall of Fame game, return to California for their second preseason game - possibly against the Raiders - and then return to The Star in Frisco for the remainder of camp. Jerry Jones said Saturday that fans will be allowed to attend practices at The Star. ... Jones had no interest in talking about Oklahoma running back Joe Mixon, who was not invited to the scouting combine after pleading guilty to assault charges in Oct. Jones simply responded, "We got our back," referring to Cowboys running back Ezekiel Elliott, who ran for 1,631 yards and 15 touchdowns during his rookie season.
