Thanks to major tools like free agency and the draft, NFL teams can make major leaps in the win column quickly.
While a bit of an extreme example, last year the San Francisco 49ers rebounded from a four-win season to put up 13 and take a trip to the Super Bowl.
Add in factors like health, developmental arcs and more to free agency and the draft, and it's not hard to see why a handful of teams can pull off massive turnarounds each season in the NFL.
This year, three teams stick out as obvious win-total jumpers.
