Unitas was injured in preseason and was on the bench most of the year. Morrall was the backup who then started in his place. Unitas did play in SBIII, but Morrall was the starter and therefore the loser. Morrall was also the MVP.
I came across this quiz 2 days before the super bowl in 2025, almost hit "start", but then I realized it was kinda pointless since it would be reset shortly anyway. So I left it open in a tab, refreshed it right after I got home from the super bowl party I went to, and it was already updated, haha.
