Each week we'll take a look at which offensive players helped put their team in the best position to win their game.

At numberFire, we dive beyond just box score scouting and the stats accumulated and look at how each player's performance affected the outcome of the game.

To do this, we'll look at numberFire's signature metric -- Net Expected Points (NEP) which quantifies the number of points a player adds to his team versus how he's expected to perform. When a player rushes for 5 yards on a 3rd-and-3 and keeps the drive and potential for scoring points going, he'll add more to his team's expected point total than when a player rushes for 5 yards on a 3rd-and-9 and forces his team to punt. You can learn more about NEP in our glossary.

After an exciting week that featured some spectacular individual performances, who were Week 15's NEP Superstars?
