Adam Hoge basically blew this theory out of the water yesterday, mentioning how
(1) you have OC candidates who literally don’t have a job right now, so yes, they could absolutely join a situation where the HC’s future isn’t guaranteed.
(2) almost no head coach’s future is guaranteed.
(3) you have OCs who either don’t call plays or wouldn’t mind stepping out from under the shadow of their own head coaches or OCs, would might take a chance on the Bears job where they’re the head coach of the offense **and** can call their own plays.
