Giants Fans Crying May Be the Most Pathetic Thing I’ve Ever Seen

What year was this? I want to look at the standings. How did he not win his division if he had the best record in the NFL? Wouldn't he have to have the best record in whichever division he was in if he had the best record in the NFL? Explain what I am missing please.
1967 He was 11-1-2 tied for first with the Rams who got to go to the playoffs on head-to-head tie breaker.

So he had the best record in the NFL but did not win his division.
