the small players train passes faster than higher, where it is written?
Something to keep in mind: as in the real world, younger players will improve more quickly than older ones, and taller players will train faster in some areas while shorter players improve faster in others. You'll have to take advantage of this information to optimize your training routine.
From BBMark, "We do give taller player bumps in rebounding, and shorter players bumps in handling in terms of how fast they train for example."
