This is the last offseason we'll have the ability to sign a major free agent without getting rid of anyone major already on the roster. (FYI I don't consider Kelly major.) We have to use it this summer or that asset will wilt and disappear. I am not a huge fan of Hayward due to his defensive shortcomings, but we gotta sign somebody. Millsap would be good. He and Al are going to age well.
Hayward isn't bad at defense.
He's not good at it, either. I'd prefer better than mediocre defense from every position, no weak links.
I can't claim to have watched more than 5 or 6 (regular season) Jazz games this year, but statistically he was very good. These numbers are from mid-February, but here's what I found then:
Gordon Hayward is 10th in the NBA in defensive win shares, and opponents shoot 2.9% worse against him than their norm, only 41.5% overall. The 41.5% shooting allowed is 7th among starting forwards.
He's not a bad defender. In fact, statistically he's better than Jae, and ranks among the top tier.
Hmmm. That indicates he's better than I thought.
Also look at it this way.
People knock on IT because even when he may score 30, he gives up just as many points on defense.
But Hayward DOES NOT HURT YOU on the defensive end, and so if he scores 25-30, he won't give it all back on defense.
That's not to say Hayward>IT, but Hayward is one of the better scorers in the game today, an all-star, and in a sense, an above average defender.
Maybe not as elite as Bradley, or Draymond, or Leonard, but still above average.
