As a Nets fan I'm okay with this player movement, I would want a 1st round pick as well but I'm unsure if I'm being bais.
To give up Kuminga just for MPJ on an expensive contract hurts, as to get MPJ; Kuminga, Moody, and Buddy are necessary contract matching. So my thinking is Cam is definitely a needle mover that can compensate the overall lose of talent.
If you disagree with Cam specifically I can understand you could just throw any 5 million dollars player to add to the compensation instead of Cam
