I think any win in the NFL is a good win. NFL isn't college. The difference between a good NFL team and bad one is small.
And I kinda get people being thankful the Bills are competitive against a good team. The defense was, but the offense was terrible. The Baltimore defense bullied the crap outta the Bills. If you take away all the bonehead Baltimore penalties, its even worse. If I use your "eye test", I saw the Bills offense get taken to the woodshed. So, not sure where all the positivity is coming from - even from that perspective.
