I suggested something a lot more aggressive when tanking became a "thing". 10-1, 9-2, etc, etc. And 16-11, 15-12......
It was rather unpopular in the forums.
Truth is, it might do more harm that good. You don't want teams losing games at the end if they're playing a team in contention. But, if you're sitting at 13-10, I think owners would be more inclined to drop from 13 to 10. You might have 5-6 teams in that group all doing their best to lose, or win, over the last dozen games.
