The question is will this be a temporary slowing of growth, which will revert to the original trend line of China tensions soften, or if the line has permanently shifted downwards?
If it’s temporary, teams that were planning on being in the tax next year likely won’t alter their behavior too much. It will increase their tax bills a little for a single season, but their long-term plans won’t change. Think Golden State as an example.
For teams like the Celtics, who were right on the edge of being a tax team, the tax will now be more difficult to avoid. The Celtics will need to consider whether they’ll just accept being a tax team (and be subject to the repeater tax the following season) or if they’re going to try to stay below it. If it’s the former, it could find them willing to take on long-term salary at the deadline that they otherwise would have avoided. If it’s the latter, it increases their incentive to move a non-rotation player with guaranteed money next year at the deadline (Poirier being the most obvious candidate.)
If it’s long-term, it will affect many more teams, as teams have been targeting the summer of 2021 already. That won’t likely affect trades in the next week, but could have a sizable impact on the summer and next year’s deadline.
