Inept trading skills of the CPU? Some NBA general managers are just as inept.
Take that Dwight Howard trade (from Magic to Lakers) from last year. Had an OS user posted that same exact trade before it actually happened, these forums would rip him apart for it being "unrealistic." They would say the deal is unfair because the Magic wouldn't be getting enough back to make the trade "fair."
It makes me laugh when people try to propose "fair trades" because it
rarely works out in the NBA that a trade is fair and benefits both teams equally. Real GMs try to win every trade they make. "Fairness" is not part of their business. If you want a true "sim," act like a real GM and try to do what is best for
your team. Forget about the other teams, they aren't your concern.
Pretending that GMs would only make "fair trades" is more unrealistic than most of the proposed trades I see get shot down on these forums.
My advice to the OP about his Suns rebuild, shop Gortat, Dragic, and anybody else for the max value you can get. That's how the real Suns GM would do it.
