GPT-Astra NFL Player Video Analysis

Rob Sandhu posted on X that he gave GPT-6 Astra NFL game film and asked it to clock Marvin Harrison Jr., with yard lines and frame timestamps yielding an estimate of roughly 15 mph downfield on a touchdown stretch. Sandhu noted the figure is a video estimate, not Harrison's top speed, and said the frames and math are included in the post.
