I recently saw on twitter a scout visual showcasing the statistic drop percentage for quarterbacks, but I have always considered drops to be a garbage figure, so this caught my attention. Intrigued by this being shown and my preconceived notion being incorrect, I embarked on a quest to uncover the truth through using some basic data science techniques. Together, we'll peel back the layers of this statistical onion and uncover the hidden truths that lie within the realm of drops. Let's kick off this study and get into the data.
