I doubt Durant made any difference in the game at all. He played a total of what 12 minutes? Dude scored couple baskets and that helped them for sure since he carried at least a quarters worth of scoring help plus allowing others to rest for a while but he wasn't the factor that changed the whole game.
Draymond on the other hand played such a great last minutes that dude managed to score a three when Iggy was afraid of shooting and made it, he scored a left hook off balance and helped his team 5 points that way while Kawhi was scoring couple times in a row so he kept the difference close, plus he blocked (lets say his fingers grazed the ball) the last shot so basically even though I hate Draymond dude won them the game.
