I lost by one point, partially due to getting a -2 from Chris Thompson's fumble on ST. For some reason, our players can get hit for turnovers on ST, but we don't get any of their points for yardage or TD's. Bullshit if you ask me. I am demanding that rule is changed next year.
Maybe it's different on ESPN, but I don't think Yahoo!'s settings are that customizable. A fumble loss is the same stat whether it was on a return, run, pass attempt, or reception. You can set it up so players get credit for return yards and touchdowns, though. I actually prefer that and going with only team defense stats rather than D/ST.
