The big reason is that the Jazz can run a lineup without a PG using Hayward, Hood, Ingles and still do as well as normal offensively. They can even add a fourth wing with Johnson or Diaw that makes the switch mismatch hard to find because there isn't a player under 6'5" that has to switch onto Lebron and there isn't a lumbering player that has to switch onto Kyrie. Also, the players not involved in defending the screen are able to stay home with Cleveland's shooters. Most teams don't have this flexibility. That is not to say that Cleveland won't still have their moments, but the Jazz can match up as good as any teams, especially with Gobert patrolling the paint behind them.
