Understanding how we calculate Waivers

We have an additional help article that describes Finding Free Agents and why it is best to utilize all sections when researching free agents.

In the Waivers section we combine their recent performance numbers with their trending ownership percentages. We call this their F+ rating, and players are sorted by this number by default. This will highlight players who have been on a hot streak recently, have been climbing in ownership, or a combination of both.

Fantasy Football, Defining "Weeks"

You will also notice that it includes the term 'Weeks' for fantasy football but at first glance this may be a bit confusing. When calculating waivers we default to using two weeks worth of data. When you are selecting 2 it is actually grabbing the past two weeks worth of stats to calculate the best waivers. Typically using two weeks worth of data allows a safer calculation of the best waivers but feel free to play around and pick the amount of weeks you are more comfortable using. For fantasy football, we suggest using either 1 or 2 weeks worth of data. (A lot can happen in a given week.)

Fantasy Football: Weeks

Now let's define some categories that we have listed that aren't too common: TRUST, O/S, F+, and FSP.


Most of the stat columns you'll find are fairly straightforward except when you come to a few specific columns. One of which is the TRUST category. We define TRUST as the likelihood of a player meeting or exceeding their expectations. Also known as consistency ratings. In order for consistency ratings to be calculated a player will need to have at least 3 games played for football and around two weeks worth of games for all other sports.

Keep in mind a bad player can have a good consistency rating if he consistency puts up poor numbers. A classic example of a player with a poor consistency rating is DeSean Jackson. He is typically a boom or bust type of player.


This simply stands for OWN and START percentages in that specific order. This is an easy way to see what players have higher own and start percentages than other players at a glance.


As previously described above, the F+ rating combines fantasy points with roster movement. This rewards players who have been rising on the waiver wire without getting the points to show for it. Think of that as being a handcuff to a top running back or a rookie who has yet to be called up in baseball. Both of those types of players will get featured in the Waiver section even though they do not have the points to show for it.

A player who is rising in own percentage and is putting up points will likely rise to the top and be one of the most sought after free agents. It also penalizes players who have a declining own percentage. For example, a star player who just got injured and is out for several weeks.


The FSP is sometimes referred to as the player rating. Player ratings calculate the value of a player compared to others and powers various tools on SI Fantasy. Player ratings are calculated based on dozens of categories, past performance, future performance, projected rankings, and a lot more.

Just because a player may have a low rating does not mean you should ignore him. If a player has no stats, then he will have a poor rating.
