The Utah Jazz haven’t had a villain quite like Gordon Hayward for a while, maybe if ever. While Utah has had its share of Benedict Arnold type moves, they usually were players who the team had already collectively moved on from or were out of their primes. Karl Malone went to the Lakers, but Stockton had retired and it seemed weird to have one without the other. Carlos Boozer left for Chicago, but he was transparent—almost painfully so—that he wanted to leave Utah after his contract was over.
The last possible “villain” who was a star player for Utah was Deron Williams who never left on his own accord and was traded.
