I feel like this is a simple question. I have a few guys with a good Speed rating, but only an average Stealing Bases rating. I have tried to make them steal more (which they have, whether they get caught or not), but from what I have noticed their rating hasn't really increased. For most players it has actually gone down slightly, but a couple have stayed the same or very slightly increased. Is this one of those random player development things? Or can it be affected by trying to steal more like other ratings can be affected by more playing time?
Thanks in advance.
EDIT: I guess this applies to bunting and sacrifice bunting as well. I have had the same experience as with stealing when it comes to those ratings.
