I actually like this list. The biggest thing that stood out is that 3 of the top 4 divisions are playing in the AFC. I think we will see a really big gap between the two conferences this season.
As for the NFC North, I think 4th out of the 8th division is a fair ranking. This is where I would put them as well. With Khalil Mack and Devante Adams moving out of the division, it has gotten weaker this off-season.
