I don't know, man. Luck is the Pelicans winning the lottery; it's defying the odds by chance. What the Raptors did was put themselves in a position to compete and then succeed. There are tens of thousands of variables in sports--which is why they entertain us--but that is what sports are made of--variables, ie "fine lines". By your definition, sports are essential luck, which maybe they are, but then isn't practically everything in life? Here's an easy test of the theory: if Kawhi's shot had swished, we wouldn't even be having this conversation? No, we wouldn't; we'd say: "What a shot!" like we did about Dame's shot. But since the shot hits the rim a few times, it sometimes loses credibility and becomes lucky? Also, no. But I get your point.
