For how long? I mean, if by “history” you mean recent memory then sure. Beyond that, though, no. Time erodes factors like that.
Do you currently make a note to yourself that Alabama’s 2010 national championship was marred by Colt McCoy’s injury? That Kyrie Irving was injured when the Warriors beat the Cavs to kickoff this dynasty? There are tons of examples like this in sports, and in the end a championship is a championship. The Warriors still have Curry, Thompson, and Green. I agree they are quite beat up and KD is a huge loss, but ultimately history will not care. Should the Raptors win, the story is Kawhi Leonard’s greatness and a team that won its first NBA championship - not an injury to the defeated Warriors.
That said, I think tonight’s toll will take a huge toll on the Raptors. They had a six point lead and monumental momentum in their favor with three minutes left (and the ball) when their doofus coach called timeout for no apparent reason. It was almost like a need for extra attention and adulation. It made zero sense. From that point on the Raptors clammed up and the Warriors shanked them. With or without Durant, the Warriors are a team you can’t let off the hook. Huge loss for TOR.
