It will be called every time if defender has contact on shooters landing. It does not require the shooter to so straight up or backwards. It is a foul if defender has contact as shooter is landing. No reason to stay pissed when the official was dead right. Learn the rule rather than bitch and cry crooked sorry, cheating refs.Yeah but he jumped forward and landed within the 3 point line. His “landing space” was behind him! There should be no expectation of room to land if you jump forward. The defender has the right to that space.
