Warriors forward Jonathan Kuminga should look into whether the same claim can be made in NBA contract negotiations. Only one thing truly, assuredly came out of this process: Kuminga’s in-over-his-head agent made Steph Curry very, very mad. “I don’t listen to agents or anybody speaking on behalf.”The quote isn’t just a soundbite; it’s a public execution of the agent’s credibility in this league. The Warriors don’t have to tear up anything. Kuminga is nothing more to the Warriors than a trade piece — one that’s eligible to be moved come Jan. 15.
