You stay put at 9 and see who falls. If the big 4 are gone, then try to trade down for the next QB the staff likes. We apparently like Hooker. By staying put we're not risking future draft capital, and we're ok if Hooker poops the bed. We can find another QB with the 2024 or 25' draft.
When you try to trade up you run head long into negotiations with teams that have a lot of offers, and they see you as QB desperate. Not good. And losing future 1st round picks for QB who might flop horribly is an extreme gamble. If he's bad the whole Panthers staff is in BIG trouble, and we have no 1st for 24' and possibly 25'. Hell no. Don't do that.
