I agree with not wanting to trade down and still draft a QB, if you are going to replace Fields via the draft you do it with Caleb Williams and hope for the best.
However, I disagree about "rip the Fields band aid off". At this point, Fields is a starting NFL QB, and sometimes I wonder if other GMs want Chicago to trade him because the market will be bigger for him (and cheaper) than Williams. Baseline is a 3rd rd pick for those teams and you have Justin Fields in that trade...at worst. the other way is you trade your entire future to the Bears to land Willams and hope for the best.
