Moved to 2005 General Issues. The thread is about the actual game rather than it is of patching.
And yea, they range from 0-99 rather then 50-99 like it was in previous years.
It is like you said, the really slow players, often centers, have a very low speed-rating down there not far away from 0. It all works gradually on how they are, and offers more detailed rating-attributes.
I don't think any player has speed in the 0-10 range.
Some stats have players in the 0-10, for instance some point guards have a 0 or 5 dunking rating, those that cannot dunk at all even unguarded. Some big men have a 0 3-point rating.
But for really basic stats like Speed or Field Goal, you don't see anything below 40 really.
