WHY UTAH DO THIS THEY get a primary playmaker and a reliable outside-the-arc shooter. This helps the young core they have to push for more wins. As Utah have a really talented core now it's better they push with a 29-year-old vet.
Why Hornets do this The Hornets have Miller and Lamelo who still need time to fit into the NBA. As a result, they have time to test out the true Collin Sexton. They also get draft capital in this trade.
