One trick I've tried on gloves that have a badly chafed palm lining, cracked and peeling to the point of leather flaking off, is to use Franklin's "Doctor Glove" foam conditioner.
If you've never used this product it is a foam, looking like shaving cream, that is formulated with lanolin and neats foot oil.
Since it comes out of the can as a foam, it can be applied to a large area with little or no rubbing. I will apply a layer of the foam, without actually touching or wiping the rough leather surface and allow it to absorb overnight.
The lanolin, of course, is good stuff for leather. The neats foot oil, besides softening, will cause the leather to darken slightly. This darkening effect can can be asthetically pleasing, as it can lessen the contrast between the darker surface leather and the lighter layers underneath.
This method seems to prevent further deterioration in the leather, eliminate the need for rubbing or wiping the damaged area and increase the eye appeal of the damaged section.
But I've never tried it on a basketball!
