ENGLEWOOD, Colo. -- There are two ways to build a coaching staff in the NFL.

There's the make-sure-everybody-knows-I'm-the-lead-dog method, where where the staff doesn't include many -- or any -- assistants who have been coordinators or head coaches in the league.

And then there is Denver Broncos' coach Vance Joseph's approach.

"I love our staff. I wanted guys who've been through things, and I think we have a good mix of youth and experience," Joseph said. "But you want to make decisions with the best information possible, and I think our staff enables us to get the best information possible, so when I'm in a position to make decisions, I make decisions that give us the best chance to do what we all want to do -- and that's succeed."

And as the Broncos work through a quarterback competition and install an entirely new playbook on offense, Joseph's and offensive coordinator Mike McCoy's willingness to let plenty of cooks into the football kitchen is visible. The Broncos have not one or two, but four assistant coaches on the offensive side of the ball who have called plays in the NFL previously in their careers -- McCoy, quarterbacks coach Bill Musgrave, offensive line coach Jeff Davidson and tight ends coach Geep Chryst.

While that might give some pause for the potential stylistic clashes, McCoy says he embraces the idea every day.

"When we first came here and Vance and I first sat down, he had some guys in mind he wanted to bring in, I had some guys in mind I wanted to bring in," McCoy said. "And then we put a phenomenal staff together. Billy [Musgrave] brought me into the business back in 2000, and I've worked with a lot of them before. This is our offense, as a team, and when we talk about working as a team, that isn't just for the players."

McCoy, who had been the Broncos' offensive coordinator on the staffs of Josh McDaniels and John Fox before his four seasons as Chargers head coach, has worked with Davidson in two other stops in the league. Musgrave was the Panthers' offensive coordinator when McCoy began his coaching career as offensive assistant.

Musgrave, who has also called plays for the Raiders and Vikings, and Davidson have also worked together on Minnesota's staff. And Chryst, who has called plays for the 49ers and Chargers, and McCoy worked together with the Panthers, as well.

Davidson was a fifth-round pick by the Broncos -- in 1990 -- and has been an offensive coordinator for Carolina and Cleveland.

"I feel like a lot of those guys have been in the league a while and know what it takes," wide receiver Demaryius Thomas said. "I kind of feel like this offense has a lot of what we did when [McCoy] was here last time before Peyton [Manning] here and after. But I think all of those guys bring a little something to it -- [Davidson] coached with A.P. (running back Adrian Peterson), so you know how they ran the ball."

The proof will always be in what happens after Labor Day on the Broncos' docket, but McCoy said their best chance to repair the offense rests in the choices made after listening to all of the ideas on the table.

"Hey, look, that first offseason is always tough, putting everything together, building everything, figuring out how we're going to call things," McCoy said. "... I'm going to listen to everybody, get everybody's input, and it's my job to make that decision about what we're going to do."

There's plenty of work to be done. The Broncos have yet to choose a quarterback and could have as many as four new starters in the offensive line.

And the struggles up front last season were the root of the team's first playoff miss since 2010 and rippled all the way through the offense. Quarterback Trevor Siemian had shoulder surgery after the season because of the pounding he took in 14 starts, and the Broncos finished 27th in rushing, 22nd in scoring and 21st in passing.

"We're working, and it's been great," McCoy said. "It's great to have those guys who've been in those shoes, called games. They see things; the more eyes you can put on something, the better. ... I'm going to talk a lot on the headsets a lot during the game. It's no different for us than it is the players. It's all about communication and getting in position to win."
