Challenges

• Unlike the rest of the data in this database, challenges are reported at the three-man crew level and not the individual referee level. The data simply is not good enough to identify which specific ref made the call that triggered the challenge.

• Challenges triggered by an out of bounds play, goaltending, or basket interference are reviewed by the replay center. So refs that have a high overturn rate are either overturning their own crews' calls, or the replay center is, or both. But we don't know which based on the data we have.
