Thats what I said last year, I said Gordon and MPJ both on the defensive side of the ball played outside of their norm. Gordon is a great wing defender and he's strong, but he wont ever be able to set his feet to be a rim protecter. He's always on help. He's why Joker's defensive numbers look better. Last year he made insane plays, a lot like Wiggins did on the Warriors. They're both similar level players. Great athleticism and strength but inconsistent as hell.
Yes, the Suns had issues in the paint defensively this season. Nurkic is absolutely not pulling his weight on that squad as a rim protector. Before he was at least decent. Now he's atrocious. I don't know how you remedy that. You can say coaching but a lot of rim protection is being intelligent and just being int he right spot.
