Hard to actually understand what you're asking, that's seriously bad english.
The Yahoo system gives less points for yards than nfl.com or espn.com leagues, making actual scores more valuable.
Best way to explain is this.
Two running backs, one runs for 100 yards with no touchdowns, another runs for just 20 yards but gets in the end zone.
In nfl.com/espn the 100-yarder gets 10 points as they award 1 point for every 10 yards rushing. The 20-yarder + touchdown gets 8 points, 2 for the yards and 6 for the TD.
Now in Yahoo it's a bit different. The 100-yarder gets 5 points, half what he would have got elsewhere as they award 1 point for every 20 yards rushing. The 20-yarder + touchdown gets 7 points, 1 for the yards and 6 for the TD. He still has fewer points but his points value relative to the other guy has increased.
I'm considering switching the league to nfl.com next year, and not because I did better there. I think the Yahoo system is too stingy on yards and the nfl.com one looks nicer!
