Should have traded him the moment he started acting normal.The nets held onto Kyrie because he basically had no trade value because he was acting like a lunatic. It seemed like he had settled down and he may have gotten than massive extension in the offseason if he stayed out of trouble the rest of the year but some people just can't help themselves.
He still had some trade value. Nets got greedy instead of just selling when they could. They can still sell him just fine. Utah will gladly help.
