How do you handicap this? You can't just say Durant is set at 34, other players are at 20 so the line is 5 points off. There are countless possibilities and combinations for this prop. Pretend the prop was OKC highest scoring player -9.5 vs all the players in all game 1s in all 4 semis, with countless players set around a max of 20 (for the sake of argument). Then it would be against a much larger field. Even though Durant is predicted to score 15 points more than the next guy, there are much more possibilities for one of them to go over. How does field size affect this play? Interesting probability thought exercise.
