CEO Jed York, appearing on the NFL Network on Friday morning from the Super Bowl in Arizona, said he expects the 49ers' new coaching staff to implement an offense that enables quarterback Colin Kaepernick to be a nightmare for opposing defenses.

York confirmed the promotion of quarterbacks coach Geep Chryst to offensive coordinator of Jim Tomsula’s first coaching staff. The 49ers had not previously made any announcements of the assistant coaching positions.

“With Kap, you got a guy in Geep Chryst who knows him better than anybody else,” York said. “You have a great guy in (quarterbacks coach) Steve Logan who is coming to come in to work with him on fundamentals and allow us to put together a system that’s going to put Kap in the best position to make plays.

“How many quarterbacks in this league can run 90 yards for a touchdown? I can’t think of many. But you have to put Kap in a position where he can make those plays. And put Kap in a position where we can run the ball (and) we can throw the ball in ways that allow him to be successful and let him be the absolute stud that he can be on the field. And I think that’s what you’re going to see from us next year. Defenses are not going to want to play against us because you’re not going to know where we’re going to hit you.”

York also confirmed the appointments of Eric Mangini as defensive coordinator, Chris Foerster as offensive line coach and Tony Sparano as tight ends coach.

“What a lot of people don’t get is you have Geep as your O.C., you’ve got Eric as your D.C. – both guys that Jim Harbaugh hired,” York said. “I think that’s a testament to Jim Harbaugh that we are keeping a lot of continuity from his staff that had a lot of success. When you look at Geep, he’s the closest to our quarterback out of anybody on the staff. You look at the guys on that staff. Chris Foerster is an unbelievable offensive line coach. He’s been a coordinator. Tony Sparano, he’s been a coordinator. He’s been a head coach. You have (running backs coach) Tom Rathman. You got Steve Logan, who’s a great teacher. You have a lot of people who are there. And you’re going to have people who understand what we do well and put our players in a position to make plays.

“It’s very simple. You look at Seattle. They have a fairly simple philosophy on both sides of the ball. But they let their players make plays. There is something to be said for that. I think you’ll see a lot of that from us. You’ll see a lot of intensity, a lot of competition, but put our players in positions to make plays.”

York defended the promotion of the relatively unknown Tomsula to take over after the “mutual parting” with Harbaugh.

“You don’t get it unless you’re in the building,” York said. “But if you’re in the building, you know. I think that’s the only thing I can tell you, other than we’re here to win. We’re here to win championships, and I don’t expect that to skip a beat.”

Coming off an 8-8 season and the first time the 49ers did not make the playoffs in four seasons under Harbaugh, York spoke about his expectations for the 2015 season.

“I expect to see a team that’s going to work every day to improve,” he said. “I’m not making any projections about where we’re going to be. I think you all know very clearly what my opinion is, and the only thing that’s acceptable. I learned that from my uncle (former 49ers owner Eddie DeBartolo). And if you don’t set your standards as high as they can possibly be, you will never achieve them.

“The only thing we’re trying to do is learn, teach, grow, understand who everybody is on our team and put our players in positions to make plays. Ultimately, they’re the ones who are going to win games. We’re going to do everything we can, give them all the resources we can to make sure they have every opportunity to be successful and ultimately win Super Bowls.”

York stressed during the interview that Harbaugh was not fired as head coach. York even cited the reports before the 49ers’ final game of the season that there was already an agreement in place for Harbaugh to become head coach at the University of Michigan.

“When you mutually part ways, there are two sides to it,” York said. “I realize people don’t want to look at it like that. They want to say, ‘Jim was fired.’ That was not the case. Jim signed on at Michigan very shortly after he left. Obviously, there were announcements before he left that he was going to Michigan. He obviously had a tie to his alma mater.

“There were things there, and it wasn’t that we just couldn’t get along. There were things on both sides. And I think he’s going in a direction that’s going to be very successful for him and his career. And I think we’re going in a direction that continues a lot of the things that he helped put into place. And we’re going to take it to the next step. And I’m very excited about where we are.”

With the coaching staff nearing completion, York said he does not anticipate the 49ers changing their philosophy toward putting together their roster. The 49ers have not been active on the opening stages of free agency with big-money investments.

“Our position has always been to try to re-sign our own and try not to be big spenders in free agency,” York said. “I think there are some great guys on this roster we’d love to have back. And those are conversations we’re going to have and details we’re going to figure out over the next couple of months.”
