What Does ROS Mean in Fantasy Football: Understanding Rest of Season Rankings

In the realm of fantasy football, understanding various terms and metrics is essential for making informed decisions about your team. One term that often pops up is “ROS,” which stands for “Rest of Season.” In this article, we’ll delve into what ROS means in fantasy football and how it impacts player rankings and evaluations.

What is ROS in Fantasy Football?

“ROS” stands for “Rest of Season” in the context of fantasy football. It refers to the projected performance and rankings of players for the remainder of the NFL season. ROS rankings are a crucial tool for fantasy football enthusiasts as they help guide decisions related to waiver wire pickups, trade proposals, and overall team strategy.

Determining Rest of Season Accuracy: The Process

Understanding how experts determine the accuracy of ROS rankings can provide valuable insights into the reliability of these projections. Let’s break down the process step by step.

Step 1: Data Collection

The accuracy analysis begins with the collection of data. Experts’ ROS rankings are captured every Tuesday during weeks 2 through 16 of the NFL season, around 5pm ET. This timing ensures that the evaluations are based on fresh rankings that have the latest advice for waiver wire claims and trades. Notably, week 17 is excluded from the analysis due to the unique nature of the final week of the season.

Step 2: Player Pool Determination

The next step involves determining the player pool for evaluation. The Rest of Season Expert Consensus Rankings (ECR) and the actual fantasy leaders of the season guide this process. A distinct player pool is established for each weekly ROS ranking assessment. This approach ensures that all relevant players are considered, including unexpected breakout stars and disappointments.

For instance, in week 2, the player pool is derived from week 2’s ROS rankings and the fantasy leaders from weeks 2 through 17. Similarly, in week 3, the pool includes players from week 3 ROS rankings and fantasy leaders from weeks 3 through 17. This comprehensive approach covers the entire spectrum of fantasy-relevant players.

Step 3: Scoring the Experts’ Predictions

The experts’ accuracy is evaluated across 15 sets of Rest of Season rankings submitted throughout weeks 2 to 16 of the season. The accuracy scoring takes into account the weightage of each week’s rankings. Earlier weeks carry more weight in the accuracy computation to reflect their greater significance for fantasy owners.

For instance, week 2’s Rest of Season rankings are assigned a weight of 15 in the calculation, while week 3’s rankings have a weight of 14, and so on. This approach aligns with the idea that earlier projections have a more significant impact on fantasy strategies than later ones.


In the dynamic world of fantasy football, understanding the meaning of terms like “ROS” can greatly enhance your decision-making process. Rest of Season rankings provide valuable insights into player performance projections for the remainder of the NFL season. Knowing how experts determine the accuracy of these rankings through a meticulous process can help you make more informed choices about your fantasy team. Keep an eye on ROS rankings and use them to your advantage as you strive for fantasy football glory.
