INDIANAPOLIS – Head coach Jason Garrett doesn’t expect discourse among coaches, nor does he worry about having too many voices offensively after the various changes this offseason. 

Garrett spoke at length today (Watch Video | Play Audio) at the 2014 NFL Scouting Combine about the new roles throughout his coaching staff, and he said he values the input each coach can bring.

“We feel really good about that,” Garrett said. “We believe in having good coaches. We have a philosophy on offense, we have a philosophy on defense we believe in. We have good coaches to implement that. We expect them all to work together like we have. We emphasize team so much with our players, it’s the same thing with our coaches. If you have the right kind of guys, they will certainly do that.”

Bill Callahan was stripped of the play-calling duties and will move back to his original role with the team, helping out with the offensive game-plan and coaching the offensive line. The Cowboys made room for Scott Linehan, who will call the plays and move into a role similar to Garrett’s before delegating the play-calling duties last year.

Garrett said the circumstances aren’t much different from how the Cowboys or other teams have operated in the past.

“Scott’s role will probably be very similar to the role I had for a number of years – passing game coordinator, play caller, working with the run game coordinator and offensive line coach,” Garrett said. “It’s been Tony Sparano. It’s been Hudson Houck. It’s been Bill Callahan.

“The situation on offense will be probably very similar to the first year Bill Callahan was here. It’s very conventional and something our guys understand.”

Callahan wasn’t let go, despite other teams’ interest in him as an offensive coordinator and play-caller. Garrett said he values what Callahan can bring as a football coach and said he’s as good a coach as he’s been around. Callahan will move back to working more closely with assistant offensive line coach Frank Pollack.

Garrett said every decision is made in the best interest of the team and that everyone understands that. Callahan’s coached the offensive line for most of his career, and he thinks that’s a great role for him working alongside assistant offensive line coach Frank Pollack.

“We’re going to back to the structure that Bill was comfortable with originally when he was hired,” Garrett said. “That’s just something we all have to embrace. It’s going to take a little time to work through that and that’s what this offseason is for. You work through the things we did well last year, the things we’ve got to improve upon and everybody has their role and the responsibility to embrace it and try to become a really close staff and a really close football team.”

The addition of Linehan gave Garrett a coach he was familiar with from their time together in Miami in 2005. Garrett said he learned a great deal from Linehan during that time and that the two share a similar offensive philosophy. In addition to his role as play-caller and passing game coordinator, Linehan will also be asked to work with Callahan and the rest of the offensive staff in putting the running game and the whole package together in preparation.

“His quarterbacks have always played well,” Garrett said. “He’s had teams where his runners…They’ve been a top five rushing team. He seems to always get a big-play receiver to play very well for him. So we feel like philosophically we are on the same page. We’ve worked together. I understand what he’s trying to get accomplished, how he works day to day, how he calls a game. So for a lot of reasons, we felt this was a really good fit for us.”

It doesn’t sound like the roles will evolve much throughout the year. Garrett said he expects the transition from Monte Kiffin to Rod Marinelli to be a smooth one, given their shared philosophies, and he believes he has the right people in the building on the coaching staff.

“We feel like we have a good idea of what we want to do. we have outlined those by title and by responsibility. We have a clear idea of that. Guys are working together throughout the spring, implementing the plan is an important thing for us. We are in midst of that plan right  now.

Here are some other notes Garrett touched on Thursday in Indianapolis.

• Garrett still anticipates Tony Romo to be ready for the spring and be involved in “a lot of the stuff we do in the spring with OTAs and on field work.” He said Romo looks good in his rehab.

• Most of Tony Romo’s energy and attention has gone into rehabbing his back, according to Garrett, but Romo has met with Linehan and had conversations about the season. Linehan’s spending more of his time getting acclimated with the coaches.

• The future of Jason Hatcher remains in the balance, but Garrett’s not giving up hope in getting the defensive lineman back next year. He praised the work Hatcher did last season and said when NFL free agency starts, he wants the Cowboys to be there for him.

• Garrett raved about the addition of Mike Pope as the tight ends coach and said he’s as good a coach he’s been around in his career after spending time with him in New York. He also said Jason Witten’s excited about the addition.

• The head coach reiterated that he was happy with the team’s decision to move back in the first round and believes every one of their 2013 draft picks has a bright future with the team.

• Linehan also favored the pass in his previous stops, but Garrett said Linehan’s also been around teams that have run well, particularly in Minnesota. He said the offense is stronger up front and the Cowboys have to play to that advantage, giving the team a chance to control the line of scrimmage.

INDIANAPOLIS — When it was announced that Scott Linehan would be the new offensive play-caller last month, many wondered how Bill Callahan would take the news.

After all, this past season Callahan had handled the role Linehan would now assume. Outsiders saw the move as a demotion, and some wondered why the Cowboys were reluctant to allow Callahan to pursue other opportunities. Requests made by Baltimore and Cleveland to interview Callahan were denied.

“Everybody thinks the world of Bill,” Cowboys executive vice president Stephen Jones said. “It’s an unfortunate situation that he gets caught up in the, well, he got something taken away from him or whatever it’s going to be portrayed as. But Bill Callahan is an unbelievable football coach. We just weren’t going to give him up and Jerry [Jones] and I have a great relationship and the coaches have a great relationship with him.

“Everybody wants to go sometimes and try to do what they were doing or whatever. But when we signed him, contracts are two-way streets. They are not just for us to deal with if it doesn’t work out. And Bill is a professional;. Are you kidding me? He is working his butt off. Was he disappointed? Everybody has disappointments. I have had it. I’m sure you have had disappointments. Everybody has them.”

Jones views Callahan as an asset who helped transform the offensive line — the position group he oversees — from a weakness into a strength.

“That offensive line really shaped up and came our way,” he said.

Jones now feels similarly about the staff head coach Jason Garrett has assembled, which now features three men — Garrett, Linehan and Callahan — who have been play-callers in the NFL.

“As I think Jason used the words, I think you have to make sure everybody is in the right seat on the bus to really make the team hum,” Jones said. “I think that’s what we ended up doing. I think we got everyone in the right seat. And obviously added a big one in Linehan. But I really think we have given ourselves, with our staff, a great opportunity to improve.”
