Bears president Kevin Warren said the team's coaching hire could shift the course of the franchise for the next two decades, so there's a lot riding on Ben Johnson as he takes over.

The team announced Tuesday morning that Johnson, formerly the Lions offensive coordinator, officially signed to become their 18th head coach. The Bears agreed to terms with him Monday, winning a fierce competition for the top candidate on the market.

Johnson also interviewed with the Patriots, Raiders and Jaguars, and the last two were thought to be targeting him.

The Bears plan to hold Johnson' introductory news conference Wednesday at Halas Hall.

Johnson, 38, helped the Lions make a remarkable turnaround offensively and has been instrumental in their rebuild. The team was fifth in the NFL in scoring his first two seasons and led the league at 33.2 points per game this season.

Lions quarterback Jared Goff has had a 102.7 passer rating the last three seasons with Johnson as his offensive coordinator, compared to 91.5 before that. The Bears are hoping Johnson will develop quarterback Caleb Williams in a way that former coach Matt Eberflus and his staff couldn't.

Offensive coordinator Shane Waldron and Eberflus were fired in November. Eberflus had a 14-32 record, which was third-worst in Bears history.
