What happened on the other 2162 - 1596 = 566 reviews?
If they weren't classified as upheld or overturned what are they called?
I'm guessing these are clock malfunctions and what else?

Clock issues.
Correct shooter.
Flagrant fouls.
Unsportsmanlike conduct.
Fights.

Clear-path-to-the-basket reviews (as of this year, a definitive call on the floor doesn't have to be made): 205

Flagrant Fouls (as of this year, FF doesn't have to be called on the floor): 265

Clock malfunction: 20

Player Altercation: 44

Correct FT shooter: 32

Total: 566

Thanks for the info. My thinking is that the NBA is making a mistake in not having these calls made on the floor first and then reviewed.
They are missing out on the training and improvement of their officiating staff as well as generating more data for how many calls are made correctly and what is overturned.
Clear path, FF, and correct FT shooter situations are all calls which are simple to have made and then reviewed. Altercations involving multiple players or people coming off the bench are impossible to correctly assess on the floor without video.
Btw I think that 80% seems low for professional referees on what is tracked.

Before this year, the officials would have to call a FF or clear path foul before a replay would be triggered...and they did (as they should)...which was silly because if it was even close, you're going to go with the "upgrade" knowing you can upgrade/downgrade as appropriate...the NBA (correctly IMO) did away with the whole song and dance.

Given the number of NBA games covered, those number seem really small to me, particularly the correct shooter (once per team for the whole season). And if you know you can go to the monitor for review on clear paths and flagrants, why call them to start with. It is more palatable to most involved parties in most cases for the officials to only make that determination after reviewing the play and seeing the entire context of everything that was happening.

80% accuracy may be low, but that is 80% of a very select set of calls that are, since they are put in the reviewable category, more difficult to get right all the time. Remember, a majority of those plays were 2pt vs 3 pt and last second shots....both calls with very, very fine lines between the two results.

Makes sense. Every other major pro league has gone to a centralized replay centre. The NHL was the trend setter. The replay centre is able to look at the replay angles before the officials get the head set on.

It also provides for more consistency throughout the league.
