The play at 15:30 is just wrong....in the description. It is a block, but for reasons different than described.
The dialog says "No. 30 red, a secondary defender just outside of the restricted area, never initially establishes LGP by having both feet on the floor facing the opponent."
They then talk about jumping from position A to position B. In doing so, they freeze the action at position A with the defender having both feet on the floor facing the opponent. Huh?
It is still a block because the defender jumped towards the opponent, but it is ludicrous to suggest they player wasn't facing the opponent or didn't have two feet on the floor. The still shot they include right after that shows both of those things.
