1. Check league import issues
Go to Edit All My Leagues (in the More menu on mobile apps). For the specific league, click Details > League Import Issues. Please read this carefully, as it will report any incompatibilities between your league and Footballguys. While we have the broadest support of any fantasy site and strive to accommodate any rule in 5% of our users' leagues, some aspects of your league are not supported and are reported here.
This is usually related to scoring, so you can manually enter your scoring - see the next section...
2. Check your scoring and manually override it
Access Edit All My Leagues (located in the More menu on mobile apps). For the relevant league, select Details > Scoring.
Carefully verify this with your league. Anything different from your league should have been reported to you in the League Import Issues during step 1.
A good example is leagues that award points for yardage based on different split categories or only grant points for total yardage (i.e., combining rushing and passing yards instead of calculating them separately). Some leagues also include kick return yards and touchdowns in their scoring.
If you think that scoring explains the unusual rankings, scroll to the bottom of the screen that displays the imported scoring and click "Manually Enter Scoring."
Then, use the form there to enter the scoring for your league.
