Introducing LOSDA - Line of Scrimmage Defensive Assist

I was 8 years old when I saw my first alley-oop. I thought it was the most spectacular thing I’d ever seen. I was already a sports fanatic and I sat, aghast at such a display of sporting prowess. Even then I was prone to noticing the little things in sporting endeavor though. I remember thinking that, yes, the athletic ability of the player hanging in the air near the basket to catch the ball mid-flight, with impeccable timing to their jump, to finish with a dunk, was remarkable. But I remember being more taken with the player passing the ball.
