From what I saw Bryant brought the ball in, juggled it, secured it, got one foot down, got tripped up by the defender, started going to the ground, dove ahead, then hit the ground with the ball popping loose. I get that it's an incomplete pass. However, what if he had gotten two feet down with the ball secured prior to getting tripped up? Would that then be a catch? Or is he still in the act of catching the ball?
