You don't know that they would have done the same thing.
You're right, I don't know. But who does?
However, I just finished reading "When Nothing Else Matters" by Michael Leahy. There is an exert from the book where Jordan is shooting around with Brendan Haywood and takes him to the hoop. Haywood blocks a dunk attempt and Jordan starts to scream, "foul...foul" until he notices the press looking at the two of them. Then Jordan proceeds to storm off the court.
In Paul Shirley's book "Can I keep my Jersey?" he tells a story of Kobe blocking his shot and then telling him to get the (fill in the blank) off his court, during a pre season workout.
While I don't know that they would do the same, I'm comfortable infering that they both had similar superiority complexes to that of Lebron.
He's not the first and only superstar that is protected by a sneaker label and not the first who would try to stop an embarrassing video from reaching the public.
