Negative
Pretty sure Goff has more TDS than Darnold too. Also, a strong point of the Seahawks is the double headed running back game. Since you asked, you were better off picking up a handcuff RB than Darnold in this situation. Goff and Darnold are equal, like you said probably around 15-20 points. Nothing good but both solid options for sure. Having 3 QBs on a team is absolute trash, man. Maybe you still play with a huge 7 person bench when in that case it doesn't matter.
