No, let's not remember it that way.
The first three days of the US Open were a qualifier, just as stated. Either you qualified for the second event, a knockout event with fifteen world beaters in it, or you did not. If you qualified, then once you got there, you had to go 4-0 to win the title, and only one player managed it.
Of those who qualified for the 256 player US Open, would you make a distinction between those that went undefeated in their qualifying events and those who took a loss on route to winning their qualifier? Of course not, because in a qualifying situation, there is no difference. And so it was at the US Open itself.
No doubt in 2016, when SVB won the US Open, beating JL Chang in the final, you had a big problem with it. Chang had beaten him 11-3 earlier in the event and won far more than half of the racks he and SVB played head to head.
Finally, attributing Shane's loss to bad luck is simply revisionist history. He was outplayed.
