I'm not in the draft a QB camp, but if you are not committed to Goff in terms of beyond his current contract, now is the year to draft a QB. They can most likely do it without having to trade a pick. They would also have the ability to trade Goff next year for picks. If they wait till next year, they would most likely have to trade picks, and the best they could do with Goff is let him walk and hope for a comp pick.
