Coach's Challenge Introduced
The Rule Change
Each team received one challenge per game to trigger instant replay review of called fouls, goaltending, or out-of-bounds plays. If the challenge succeeds, the team retains it; if it fails, they lose it.
Statistical Impact
Marginal statistical impact, but improved officiating accuracy on high-leverage plays. The bigger effect was cultural — it acknowledged that referees make mistakes and gave coaches a formal mechanism to contest calls.

Replay Center in Secaucus Established
The Rule Change
The NBA centralized its replay operations at a dedicated facility in Secaucus, New Jersey. Rather than having on-court officials huddle around a courtside monitor for every review, many replay decisions were handled by a team of officials watching multiple games simultaneously at the replay center.
Statistical Impact
Reduced the time required for replay reviews and improved consistency by having dedicated, specialized officials handle reviews. The centralized approach also allowed the league to review more plays than was practical with on-court monitors alone, furthering the trend toward technology-driven officiating.
