NFL does stand for "Not for Long". The season being as short as it is, good and bad play is amplified 10x.
I think it gets harder to see the forest for the trees, so to speak, since there are not a lot of games to base decisions on in a single season, and as such, emotions tend to ride higher than if it were like a 32 game season or some such...
That said, wouldn't have it any other way....
Go BEARS !
