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.
I don't think it is down to one or two guys. It was their trust in their system that brought them back to life even after Kahwi made a good run for the Raptors. Add to that the wasteful play of Lowry.
Both teams have a great system, for the Raptors, it was not only Leonard alone but his teammates get involve as well.
It was just that people think the Raptors will beat the Warriors as the Raptors is a healthier team and as this series prolong, the advantage is on them.
The warriors can't afford to have one of their starters again to get injured so they have to be careful as even if they will win game 6, there' still last game that needs to be played on the road.
I will just enjoy the game tomorrow, and I'm doubtful on the Warriors winning game 6 although playing at home.
