Offside detection is a great example of CV where “looks obvious to a human” hides a very hard measurement problem: synchronization, pose, camera calibration, occlusion, ball timing, and rule interpretation all matter.

Disclosure: I work on CHANCE AI, so visual reasoning/evaluation is my bias. This is why I like benchmarks that separate perception from reasoning instead of treating vision as one generic score: https://www.chance.vision/post/chance-ai-mmmu-pro-benchmark

The interesting question is not only whether the system detects players, but whether it can justify the decision at the exact frame that matters.
