The Warriors don't know if or when the current NBA season will resume, much less the next one. But whenever the 2020-21 season takes place, they'll likely have used several assets at their disposal with which to return to a level of legitimate contention.
But in terms of the Warriors' asset that likely will have the greatest determining impact on their success next season, the $17.2 million trade exception they received for sending Andre Iguodala to the Memphis Grizzlies last summer stands apart from the rest.
Trade exceptions cannot be combined with others, so through the Iguodala trade exception, Golden State cannot acquire a player making more than $17.2 million (technically, it's $17,185,185.) However, trade exceptions can be split, so the Warriors could theoretically use the Iguodala trade exception to acquire multiple players, as long as their combined salaries don't exceed that amount.
While Golden State should absolutely be able to acquire a good player with that trade exception, the Dubs will have the added challenge of only having a tight window with which to use it. Once the league moratorium concludes at noon ET on July 6 (as currently scheduled), the Warriors will only have until the end of the following day to utilize the exception in a trade. They cannot use it prior to the moratorium, though in theory, they could agree to a trade at any point along the way.
Given the indefinite league stoppage due to the coronavirus (COVID-19) pandemic, it's possible that Golden State will be granted some kind of an extension to use the Iguodala trade exception, but there is no guarantee. Whenever it expires, however, the Warriors would be wise to use it on one of the following seven players prior to that point.
