An interesting perspective on records. Assuming the Vikings win today, the division will have a 30-6 record. The Lions lost to the Buccaneers, the Vikings lost to the Rams, and the Packers lost to the Eagles. The other three losses, one by the Vikings to the Lions, and the Packers, one each to the Lions and Vikings. That means the three combined are actually 30-3 on games outside the division, and there are circumstances surrounding all three of those losses that contributed to them happening.
I don't recall ever seeing a division this strong in the past to be honest. If the Packers do beat the Lions and the Vikings, and run the table, and the Vikings beat the Lions, and lost to the Packers, and run the rest of the table, and the Lions lose the two aforementioned games, and run the table, there would be a 3 way tie, with matching head to head records, so it would come down to points scored to determine 1st through 3rd place, and it could easily be the 3 best records in the whole NFL.
As for the Bears, they've lost 5 out of division games to date, of their 4-8 record. Throw the in-division losses out, and they'd be 4-5 outside the division, which is only one step below average.
An amazing season for the division.
