The training system works really well. The only problem there is, is a slight lack of options specifically for SFs and PFs (and a bit for SGs), all of whom have to play out of position to recieve most of their training. This is totally unrealistic, do we really see Miami having to play Lebron at C so he can improve or Bosh at PG. Instead there shouldbe some more training options for them. All the BBs would need to do is introduce some new training categories such as:
These are just examples, LOTS of thought should be put into any new positions to not make things too easy...
Comboguard 1 position for SGs, affects driving, with secondaries of passing and jump range
Swingman 1 position for SFs, affects jump shot, with secondaries of rebounding and handling.
Postman 1 position for PFs, affects passing, with secondaries of IS and driving
