15 INTs isn’t really an abnormal amount, it’s honestly average or or even low for a league leader. Dak’s main issues have never necessarily been INTs in a vacuum, and people have won MVP while throwing more INTs than that. No one would say Kurt Warner had a bad year in 01-02 because he threw 22 INTs.
The other people on that list have also, you know, been MVP candidates or top 5 QBs at some point in their careers, unlike Dak.
More INTs = Bad isn’t a good take if you don’t consider other way more important stats
