If the Vikings acquired Cousins, he'd be starting Week 1.
Unless Atlanta keeps him, Cousins will be starting somewhere in the NFL next year. Even before we get to unplanned injuries, there's not enough capable starting QBs to go around. Mia, NYJ, Pit, Cle, Ind, LV, AZ all need QBs and if they were smart NO and Car would be looking too. Daniel Jones gets one job, and Mac Jones possibly gets traded to another spot. I doubt Aaron Rodgers comes back, but even if he does, that leaves at least four spots and there probably aren't four draftable starters this year. Maybe some teams would take Kyler Murray and his youth and legs over Cousins, but I bet most wouldn't. Cousins would almost certainly be more desirable than Tagovailoa, and after that, were probably talking about backups like Brissett, Marriota and Wentz.
