So, look, the Lions did not win the NFC North in 2016. They went 9-7. The Green Bay Packers went 10-6. 10 is more than 9, therefore, the Packers won the NFC North.
It's been a long time since Detroit had a division champion and maybe they thought no one would notice if they claimed they had actually won the divsion:
"T.J. Maxx in Chesterfield Township is selling what appears to be an officially licensed NFL T-shirt that proclaims the Lions "NFC North 2016 Division Champions."
"About a half dozen of the T-shirts were available at the Chesterfield Township location over the weekend, on a wall with apparel for other local sports teams. Three other T.J. Maxx stores did not have the shirt in stock."
This is classic Detroit. If you believe in karma there is no way they win the division for another 23 years.
