GLENDALE, Ariz. -- Don't call Chase Edmonds the Arizona Cardinals' RB1. But don't call James Conner their RB1, either.

Neither of the Cardinals' top two running backs like the label, and as the season unfolds, it may not be apropos of either.

The two will share the very large majority of Arizona's backfield duties this season, with the likes of Eno Benjamin and Jonathan Ward also getting some snaps.

"We expect both guys to share the load for the most part," said coach Kliff Kingsbury, in his most revealing comments of training camp about the makeup of his running game. "Chase can be an everyday guy and so can James, and so we want to make sure when they do get their touches, we're getting them in situations they can be successful and be fresh and healthy."

It may be more fitting to call them RB1 and RB1A -- but even those titles will be interchangeable this year. Edmonds is listed as RB1 on the depth chart for the Cardinals' first preseason game against the Cowboys on Friday night.

While they will share the backfield this season, each will bring a unique skillset and body type to the Cardinals' offense. Both can run and catch, but Edmonds had more receiving yards last season than Conner (402 to 215) while Conner had more rushing yards (721 to 448). This season may end up mirroring those stats.

Edmonds spent the offseason refining his receiving skills, while also putting on a few pounds to reach a more lean 205. Conner checked into camp at 233 pounds.

"We'll play to their strengths," Kingsbury said. "James is obviously a bigger back. Chase, when he had [an] opportunity, did some great things, and we want to make sure we're calling plays that both those guys are comfortable with when they're in and kind of tailor to them."

Kingsbury was also quick to point out that "they can both do it all."

Edmonds isn't as concerned about the number of carries he sees or the number of overall touches.

"Whether it's 15 touches -- and that's 10 carries, five grabs -- or if it's 18 touches -- and that's nine carries, nine grabs," Edmonds said. "... Getting me in the open field and finding a way to just specialize with my mismatching linebackers is really how I believe I really feel like I'm the best type of football player.

"We've got a lot of talent on the offense and we're gonna have to find a way to spread the wealth a little bit."

Part of what Kingsbury hoped to accomplish during training camp was how to use both Edmonds and Conner together. There's already a package in the Cardinals' base install that includes both backs on the field at the same time.

"There'll be times where I'm on empty, and he's on empty, and I run the ball, he's running the ball," Conner said. "So, I really feel that we can do both."

Running backs coach James Saxon told Edmonds and Conner that they need to be unselfish this season because they're both going to play, and they're both going to make plays.

"So, RB1, it don't mean much," said Conner, who played his first four seasons with the Pittsburgh Steelers before signing with Arizona this offseason.

A couple weeks into camp and both are already showing their running personalities.

"James is more patient with it, that Pittsburgh style of running," left tackle D.J. Humphries said. "I say that Chase has that one cut, hit hole, take off. And I love that combination between those two because it's hard for a defense to settle into what they expect coming out of the backfield."

The two have been resources for each other thus far. Edmonds has been helping Conner with the playbook, the code words and the one-name plays. Conner has been giving Edmonds a different perspective on playing running back and sharing his experiences of playing in big games, Kingsbury said.

"They both feed off each other well," said Kingsbury. He added that they're both quite similar: They're both serious about the game and both "pretty stoic."

It hasn't gone unnoticed.

"Personally I think they're both No. 1 backs," said Sean Kugler, Arizona's run-game coordinator and offensive line coach. "So, I think it's a luxury but they both bring outstanding things. They're both ultra competitors, they run hard, they can catch the ball, they do a great job in protection, they're both very smart, so very excited about having both those guys for our offense."
