The Chicago Bears have made a concerted effort this offseason to be one of the active teams to build around their promising young quarterback Mitchell Trubisky. This has pushed forward some optimism around the organization that the team could take a significant step forward next season.

However, former Bears head coach John Fox voiced on Tuesday during an appearance on ESPN's NFL Live that he believes his former team's biggest challenge will come in the passing game. (h/t Dan Santaromita of NBC Sports Chicago)

“Their challenge will be their passing game,” he said. “That’s where they were deficient last year. That will be how fast they can adjust.

“Just getting all those pieces in place to be more efficient in the passing game. Young quarterback, Mitch Trubisky, how efficient is he gonna be, how fast he can get used to those pieces?”

In his rookie campaign, Trubisky had his fair share of promising moments beyond his struggles to adjust to the NFL game as he finished with 2,193 passing yards on 59.4 percent completion rate with seven touchdowns, and seven interceptions in 12 games played. He had shown to be a poised quarterback in the pocket with some mobility that could help aid him in his development in moving around the extend plays at times.

That said, the various moves that the Bears have made to provide him additional weapons in the passing game such as wide receiver Allen Robinson and Taylor Gabriel along with tight end Trey Burton should lift up the reliability there will be in that aspect of the offense. What should also keep in mind, the team possesses a dynamic duo in the backfield with running backs Jordan Howard and Tarik Cohen that could factor greatly in the equation in helping the Bears take the next step toward playoff contention next season.

There may be some uncertainty at this point in terms of what to expect from Trubisky's development heading into his second season but the pieces are in place around him to take some strides forward in 2018.
