Hayward is better than Gallinari but I think it would be only a minor step back to have Gallinari instead of Hayward if he stays healthy. We will also be a better team than the Jazz were last year with him. We need some health luck, we are due.
One of Hayward's best attributes over guys like PG is his passing abilities. However, with Rubio now on board setting the table for all the other guys, his passing may be redundant? Hence getting a score first SF in Gallinari as a consolation is really not all that bad. It's sort of a soft landing, really.
