He will, and he has to. If he holds out, that year left on his contract remains. Who has ever forced their way out of a long term contract? Buyouts come at the behest of the team, not the player. Do you honestly think it's better for the Spurs for Kawhi to have kept all of this to himself, played out his contract, then left the Spurs in a lurch next summer without having the opportunity to get something back for him? He had a terrible experience with his team, let it be known and gave his team plenty of opportunity to trade him before losing him outright. Their own refusal to accept the situation and act on it is only going to get them less in return the longer they drag this out.
