Was Kevin Durant only great in NBA Finals since he played against bad defensive teams

KD has been very productive in NBA Finals by scoring 30 points in several occasions against Heat & Cavs. But do you think its was mostly a product of the other teams having bad defenses? Never mind that KD was usually wide open and never really got double teamed? Miami Heat & Cavaliers tried to double-team other players instead. Do you agree with this sentiment?
