Fair warning I only really watch the Suns playoffs games. But I personally have not seen anything from him that places him far above even Nurkic for the Suns.

I think he himself is a net negative bc he views himself as an all-star (which he is don't get me wrong but not on par w KD/Booker). The suns need someone like Looney who's gonna hunt rebounds and get easy buckets. They need more of a role man in that position. Now he absolutely can be this man, but he's just not. He's not aggressively hunting rebounds or using his size to his advantage and often settling for mid range jumpers (which are good but again you have book and KD who are both better at this)
