When setting up yardage ranges for scoring in Leaguesync, make sure there are not any gaps in your ranges.
For example setting up your rush yardage ranges like the following:
0.000-49.000 = 1
50.000-99.000 = 2
will result in a gap between 49 and 50 yards. If a player is projected to rush for 49.5 yards, they will not be accounted for and will be awarded zero points -- not your desired outcome.
When setting up ranges like above, make sure they are configured like this instead (notice the .99):
0.000-49.99 = 1
50.000-99.99 = 2
