Why visual review is essential

There is no substitute for visually reviewing every violation like we do for the following reasons:

Violations called by multiple refs

15-20% of violations are called by two or more refs, which is only detectable through visual review. This makes a big difference in getting serious accuracy.

Illegal screens & travels

We break out which refs call illegal screens, a very important violation not provided in official scoring, as well as traveling violations (not provided either).


Official play-by-play records aren’t always correct.  Visual review of every violation ensures better accuracy.
