His arm is clearly being grabbed while he's still on the ground, making a move to the basket...
You're telling me Blake can continue driving to the hoop with the dude's hand grabbing his arm, and even have enough strength to generate lift from the ground, but as soon as he goes airborne the "pull" is enough to cause him to helicopter, land on his hands, and grab his head in a fake-ass attempt to draw a foul?
So many of you guys are delusional and only see what you want to see. Dude had his hand on Blake's arm a full step before he even jumped... How are you even going to try to defend this flop when the evidence is right there
