THere is no one like Shaq or Iggy or Baron Davis that no matter how much practice or game experience they get, their FT ability never improves.
We already have that -- caps on abilities.
THere is no athletics elements, no speed, no power, no vertical, nothing like that.
So let's look at what we DO have.
I think you are grouping a lot of things into this idea of experience and expecting the BB experience stat represent all of them
No, you're making up details that aren't in BB now and aren't needed.
At the end of the day I would be okay with an ability to train or give training to players who do not play in games to some extent. Realistically however some players can not and do not ever develop, even lose skill over time. So for me having some players on teams that don't ever develop at all is realistic.
And we have that -- caps.
Working with the parameters of how the game already is, how about minute requirement for the team training, and the selected franchise players is just automatically considered as having 48 whether he played them or not and given the training (like a very determined guy, such that he can develop even if injured for example).
I am not sold on the need to introduce this new concept just to reform training.
THis might be easier to program for Marin as well, trying to select a player alone and have the game check his minutes as a seperate workflow woudl be extra coding, but just having a bypass/automatic application of training each week to a given player selected by the user would probably be easier. For the rest of the team, the team trianing element, have it just applied as the system already works with a minute check/ratio element up to 48. In this way you would have a guy training whether he plays or not, everyone playing on the team getting development/training and maybe a few guys on the bench not playing and not developing (which if we want to make it feel realistic we can just say, maybe its that they are not working hard in practice hence the coach is not using them)
I think you may be beginning to see how difficult it is to try to justify any conection between minutes played and training. It simply isn't logical or needed.
