We're now a quarter of the way through the NFL regular season, but at times, it seems like we know less than when we started. Week 4 featured the return of Cam Newton, Russell Wilson, and Lamar Miller to prominence, and perhaps the emergence of rookie Deshaun Watson as a fantasy star.

Each week, we'll take a look at offensive players at each position who helped put their team in the best position to win. However, we'll be going beyond just the box score by diving into the impact of each player on their team's success.

To do this, we'll look at our 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 -- alive, 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.

So who were Week 4's NEP superstars?
