In-season coaching changes are a thing of the past for the Dallas Cowboys, owner Jerry Jones said.”You don’t need to worry about anybody in that locker room giving everything they’ve got and more and how bad they feel when they get beat on a play or get beat in a quarter or the whole game, at all,” Jones said Monday following the Cowboys’ seventh loss of the season. “I don’t ever worry about that.”Jones said he regrets pulling the plug too soon on head coaches in the past, including firing Wade Phillips after a 1-7 start in 2010.”I’ve regretted that. That’s the music I’m listening to,” Jones said.There are no plans for an in-season move involving head coach Mike McCarthy in Dallas, where the Cowboys (3-7) are winless at home by a league-worst margin of minus-118.McCarthy said “it’s frustrating for everybody” to accumulate losses, but he knows the only thing that might save his job when his contract runs out in January is ending the season with a string of wins.”There is good coming out of this,” McCarthy said Monday night. “You don’t see it because we’re not winning games, but there’s young men that are getting an opportunity to do more and I do believe it’ll pay forward. It needs to hurry the hell up, because we need it in six days.”The Cowboys went 12-5 last season and discussed a path to the Super Bowl throughout the offseason. Expectations did not match the current reality.Jones said he’s counting on the Cowboys sticking together through what he described as tough times, similar to Dallas going 1-15 his first year as owner in 1989.
