it was not debunked--- many just chalked it up as "no big deal".
It was debunked because it was shown not to be the defiance that the article tried to paint it as.
As @DJ pointed out. It's not really different from a QB calling an audible. He just needs to be right.
Fortunately for Lebron, he's the best player in the world, so he can make it right even when it isn't. lol
