Clearly the potential increases a player's resale value, as does having high jump shot or high inside scoring. Which is why buying a player of lower potential and training him to say this:
Weekly salary: $ 21 353
Age: 25
Height: 6'3" / 190 cm
Potential: starter
Game Shape: proficient
Jump Shot: sensational Jump Range: average
Outside Def.: prominent Handling: proficient
Driving: prominent Passing: proficient
Inside Shot: mediocre Inside Def.: respectable
Rebounding: respectable Shot Blocking: pitiful
Stamina: strong Free Throw: mediocre
makes a lot of sense for any but the top maybe 30 or 40 leagues. This player is my backup PG, SG, and SF. Not flashy but he gets the job done.
I agree also with the one-on-one training for forwards. Has been one of my favorites.
Once I scored a basket that still makes me laugh.
