The Suns are the most deadly team in the league at the shots we conceded. Ayton allows Gobert to stay in the paint, but he also occupies Gobert super well. I actually think it’s harder for him to guard a good rolling big man than it is to guard a stretch 5.
The Clippers didn’t start beating us until they stopped running PnR at Rudy. Even with a spaced plot Rudy could keep it contained by switching or keeping everything in front. It was more difficult for him to defend when Zubac was in the game because the space between the two players was greater. A deadly mid range shooter combined with a good rim running big is tough to stop. CP3 is one of the best all time in that situation and Booker is great as well.
It doesn’t make PHX impossible to beat, but that’s a tough matchup because their offense is designed to score against our type of defense.
In general, however, I think PHX’s greatest strength is just how damn good they are in the clutch. I think GSW, UTA, MIL, and maybe BKN are better teams than PHX. But if PHX can keep it close they are the best on the league in the clutch.
