I had the same dilemma as you, as I was contemplating drafting a 5 star A+ with low potential. He turned up at the start of the season like this:
Jump Shot: average Jump Range: respectable
Outside Def.: mediocre Handling: respectable
Driving: inept Passing: awful
Inside Shot: respectable Inside Def.: respectable
Rebounding: mediocre Shot Blocking: inept
Stamina: average Free Throw: strong
Now more than half season into it...
Ko Guo Quiang (23029149)
Power Forward
Owner: Likas Internets
Weekly salary: $ 4 520

(BuzzerBeta)

He will probably cap in a few seasons... but I think he will be a great backup for my team, and I don't intend to fill my roster with salary heavy guys anyway.
