Yahoo default scoring question

[moose162]

For Yahoo default scoring, don't you lose points on your DEF if the ST fumbles?

If you can get a TD from the ST why not lose points for fumbles. Sorry if this is in the wrong forum but I felt it's better here than the beginner's as it's not entirely "basic".

Nowhere in the DEF/ST scoring rules is there anything about Fumbles lost, so they don't count as anything

Similair situation is if on an interception return the defender fumbles, no scoring there either
