SAD NEWS: The head coach of the Chicago Bears has terminated his employment with the team following a background debate with management over…

Throw out what you know about the Bears’ offense.

Last year’s -4 percent pass rate over expected — the third lowest in the league — is gone with the wind. As is OC Luke Getsy. As is QB Justin Fields.

As is just about everything that defined this moribund attack over its past few lottery-pick earning seasons.

That thankfully does not include No. 1 WR DJ Moore, who is being joined by reinforcements Keenan Allen and Rome Odunze.

They will be catching passes from No. 1 overall pick Caleb Williams, who will be receiving play calls from ex-Seahawks OC Shane Waldron.

The Bears’ new offensive coordinator is a Sean McVay and Pete Carroll disciple, but the biggest influence will probably end up being Williams himself.

That’s because however much imprint an OC leaves on an offense, attempts tend to be a quarterback stat, and few quarterbacks attempted more passes over the past two years than USC’s triggerman.

Williams (6’1/214) enters the NFL coming off a “down” season where the Trojans’ line and supporting cast woes “limited” him to 3,633 yards and 30 scores in 12 games.

“Khalil Herbert may be the odd man out when the Chicago Bears clear the logjam in their backfield,” Kay said.

“After coming to terms on a three-year, $24.5 million deal with D’Andre Swift—who projects to lead a platoon that also includes 2023 fourth-round pick Roschon Johnson—the Bears will find themselves hard-pressed to keep Herbert as a little-utilized depth option.
