The Jazz know full and well what happens when you mess around with a restricted free agent.
Everyone knows about the infamous Gordon Hayward-Utah Jazz fallout. For that reason, teams have to be wary about playing hardball with their restricted free agents. One of which is currently going on is Josh Giddey and the Chicago Bulls. While that situation is dragging itself out, it shouldn't be for too long, because not only did the Jazz pay for that with Hayward, but they did so not knowing of the late-bloomer he would become.
