Imagine a world where NBA players were banned from using exercise equipment.

The league didn’t want players getting too physically dominant and subjecting themselves to the types of muscle pulls that would come with a physique arms race. Players were still allowed to train, but using any outside equipment crossed the line. Of course, some players broke the rules and lifted weights, but they risked suspension.

Seem irrational?

That’s not all that different from the NBA’s HGH ban.

Perhaps, there’s good reason to prevent players from using HGH, but Mark Cuban wants to see the research first.
