Obviously Denver has a deeper squad than Phoenix, but their real advantage lies in the positional matchups.
Jokic dragging Ayton out of the paint will be a huge advantage, as it mitigates the Suns only good rebounder and rim protection.
Porter Jr has the size and length to at least bother Durant & make him work for his points, & because Okogie isn’t an offensive threat, Gordon can double or switch onto Durant.
KCP has the defensive ability to annoy Booker.
Jamal Murray’s size, strength and quick release shot won’t allow CP3 to rest on defence.
