With the 2012 NFL season winding down, let's take one more look inside the world of playing time and snap counts via the in-depth data at Pro Football Focus.

The NFL now makes basic snap data available to anyone willing to open a game book, but only Pro Football Focus can take you far deeper into those numbers and tell you what players were doing on any given snap, where they lined up and what it means.

As we get closer to the playoffs -- and deeper into the fantasy playoffs -- let's take a look at what snap counts tell us about fantasy implications surrounding the Bills' limited use of C.J. Spiller, how the Vikings have attempted to replace Percy Harvin and how the Jets have managed their wide receivers.

The Bills' misuse of C.J. Spiller

The Bills' season has been far from ideal, but no part of it has run off the tracks more spectacularly than their misuse of Spiller, who has been on fire this season despite limited usage. Spiller has actually played a reasonable amount of snaps for the team, notching 465 snaps on the season, bettered by just 20 other running backs in the league. Plus, he's played more than 50 percent of the Bills' total offensive snaps.
