Man. I agree with you so much on this. If they do anything like this, it should only include teams far out of the playoff picture and allow teams that are in the playoff picture to rest. I don't know what the incentive would be, maybe a play-in slot or something. It just cannot add overall games for the teams already likely headed for a deep run in the playoffs.
I have often thought that the league could go from 12 minute quarters to 10 minute quarters. It would really mess up historical stats, but it would cut the season by about 16% for players. The result would be less fatigue and wear and tear. The number of games would be the same, so the gate would remain the same, and on TV you would have more time for advertising.
Its an "out there" idea, so I am sure there is something dumb about it that I had not thought of, but there it is.
