If balancing were to occur, this Guard would suddenly be somewhere in the range of 600-700 minimum. Just as monstrous a salary as any of the big men out there, if not moreso.
The argument that's occurring with the large salary thing is more that some managers are annoyed that players with large salaries are being snapped up for one or two games to clinch specific games. Balancing salaries would just make it so that those big men would be slightly more but still by no means affordable and that "problem" would continue in a slightly reduced form.
