When the Bears came calling to Davis and offered a two-year, $6-million deal in free agency, he was sold by the prospect of being a piece in Nagy's plans. Now here the Bears are working through the early practices of training camp with this offense being everything Davis had hoped.
"Matt Nagy is a genius when it comes to plays," Davis said. "You got to learn every position. You never know where you're going to be. Everything I loved in free agency about this team, it's true.
"Every day it's something different. You can be put anywhere in this offense. That's what I like about Nagy's system."
How big of a role Davis will have in the Bears' plans is still being defined, with rookie running back David Montgomery being the key factor in play.
Montgomery's development early in his rookie season could dictate whether he or Davis carry more of the burden. Davis had a career-high 112 carries with the Seahawks last season, a number that equates to 7.5 per game. Nagy views Davis and Montgomery as similar options out of the backfield, while Tarik Cohen will be preserved to use in more of a gadget role. For his part, Nagy is still unsure how reps will be divided between the trio.
The Bears signed Davis before trading Jordan Howard to the Eagles in late March. However, Howard had been informed in late February that he wouldn't be returning to Chicago, a source said. Once Davis joined Cohen on the depth chart and Howard was gone, it was only a matter of whom the Bears would draft.
Montgomery would be their man, selected in the third round after the Bears traded up to the 73rd pick.
"Nothing is going to change from what we saw on tape at Iowa State," Nagy said of Montgomery. "Nothing is going to change. He has some of the best vision that I’ve seen in a long time. He feels where the defenders are before they show up."
Nagy and the Bears will count on certain factors in determining roles for each game. Beyond rushing skills and pass-catching abilities, pass protection will also be a critical element. That's where Davis could be counted on the most -- especially while Montgomery develops that skill set.
What the running game can become will be especially important for third-year quarterback Mitchell Trubisky, who needs his dynamic backs to ensure the offense can grow after the Bears ranked 21st in total offense in 2018.
"I feel like that was one of the biggest things last year, we needed to be more consistent," Cohen said. "The defense bailed us out last year a lot. We want to do our job more often this year."
With a little more than a month until the Bears kick off the regular season, Nagy has time to decide how his running backs will rotate in the backfield, out wide or wherever else they're needed.
They're ready for whatever is needed.
"If Nagy wants me to punt, I'm going to be out here punting," Davis said. "I'm just here to do my job."
