The San Francisco 49ers stand at 5-2 atop the best division in football in the NFC West. Yes, you read that right.
The NFC West has had a stunning turnaround after being the laughing stock of the NFL for the last five years.
However, in the NFL, three years is like a millennium. Teams adapt, improve and move on. It's one of the many reasons why the NFL stands alone atop American sports.
