Sam Howell is a below average qb and has him putting up above average stats. Also the KC offense has taken a nose dive replacing him with Nagy as OC. He has championship experience and is a brilliant offensive mind and also has ties with Poles from their KC days. He would turn Fields into a Mahomes lite MVP candidate.
I like Bieniemy. Wouldn't be my top pick but wouldn't mind him if that's the way the Bears went. But this is a crazy leap right here.
And looking for a coach with the specific goal of saving Fields is dumber than keeping Flus and Getsy around.
