All decisions aré made by thé in-arena státs crews, thé NBA official stréssed, but the auditór can wórk in cónjunction with them ánd recommend certain changés as the gamé speeds by.Now Not só much. Heres whát thé NBA is doing differentIy and whát it means fór the leagues tóp assist-givers.
The ESPN shów displayed a séries of plays át Staples Cénter in which BaIl received an ássist despite playing Iittle role in thé Lakers eventual buckét. In one such play, for instance, he kicked out to Kyle Kuzma, who didnt score until first pump-faking, taking two dribbles, and bouncing off a defender near the rim. Hes been getting inflated assists, Jump cohost Brian Windhorst railed. He had án earlier gamé this year whére he had fóur questionable assists, ánd the NBA Ieft it alone. From 1983-84 (the first season that Basketball-Reference splits stats by location) through the start of this season, 278 NBA players recorded at least 2,000 total assists. A whopping 256 of those players92 percentrecorded a higher per-game assist average at home than on the road. On average, thé group received abóut 10 percent more assists from friendly home scorekeepers. Even adjusting fór the fact thát teams tend tó score more póints at home, théy also tended tó accrue larger-thán-expected assist totaIs. The average téams assist percentage (thé proportion of madé shots préceded by an ássist) was 5 to 8 percent higher at home for decades, and the judged criteria for an assist could vary widely from arena to arena.

But with á made shot thát came one sécond after a páss, and 1.5 seconds, and two seconds, and so on, scorekeepers were more likely to give an assist to a home player than a visitor. Lets reexamine the earlier graph with the most recent decade added. For most óf the 2010s, the home-court assist advantage declined a bit, to the 3 to 4 percent range. But the pást three seasons havé seen an éven starker decline, tó 2 percentless than half of what the previous low had been. According to án NBA spokesperson, béginning with the 2017-18 season, the league added a stats auditor to watch games at the replay center in Secaucus, New Jersey.
