The Warriors have two trade exceptions that expire tonight that they can use to make a move.
The club is currently about $4.8 million under the luxury tax threshold, so they could add some salary without being subject to the dollar for dollar tax.
In addition to the two expiring Trade Exceptions, the Warriors also currently hold another large Trade Exception from last year's Cliff Robinson trade, their full $1.67M Bi-annual Exception, and are only one of 4 teams to still hold their entire $5M Mid-Level Exception.
