SFU student finds you may be getting hooped

The NBA had revoked some players' triple doubles an in game achievement where an individual reaches double digits in three separate categories after it was determined some of their more dubious assists couldn't be justified.That, along with a story about a rogue NBA scorekeeper who purposely fudged numbers without getting caught while working for the Vancouver Grizzlies in the 1990s, got van Bommel thinking.The NBA states assists, the stat researchers focused on most, are given "only if, in the judgement of the statistician, the last player's pass contributed directly to a made basket."That sentence alone leaves a lot of room for interpretation, van Bommel and Bornn thought.The pair analysed billions of lines of data from NBA cameras that track the movement of copy van cleef and arpels diamond bracelet both players and the ball on the court 25 times per second in every game. Their mathematical model monitored on court actions, taking into account styles of play, while omitting overtime periods and neutral site games.They matched results to the box scores, concluding that scorekeepers have a wide range of opinions on what constitutes an assist."We quantified two different scorekeeper effects," said the 23 year old van Bommel. "There's how generous a scorekeeper is, which is how often they give assists to any player."The other side is the actual bias where there's some scorekeepers that give more assists to the home team, and some scorekeepers that give more assists to the away team."The Utah Jazz scorekeeper was found to be especially frugal with assists, awarding van cleef and arpels butterfly bracelet fake 9.7 fewer on average per game compared to the one employed by the Atlanta Hawks."We're not trying to say this is anything intentional or anything malicious," said van Bommel. "The NBA just has these ambiguous definitions, especially for assists. This leads to inconsistencies in scorekeeper opinion."So why worry about a couple of assists that don't impact the final score? In the world of big money daily fantasy sports leagues where participants select a roster to compete for cash prizes, the implications could be far reaching.According to Simon Fraser, the Fantasy Sports Trade Association estimates more than 58 million people across North America take part in daily fantasy sports."It's hard to quantify what percentage (skewed stat lines) impact your odds of winning," said van Bommel, who doesn't play daily fantasy. "But in a lot of these games a point or two can make a difference between winning and losing."A thing like scorekeeper bias can make all the difference."Rob Pizzola, who worked in media before leaving his job to van cleef fake bracelets focus on daily fantasy and sports betting full time, said the study raises interesting questions. "There's a feeling (scorekeeper bias) matters and there's something to be done with it."But we're hesitant until we know exactly how to use it or until we get years and years worth of data that's a little more stable."Apart from the fantasy implications, van Bommel said the bias could influence an NBA player's earning potential.Six of the 10 players who had the greatest negative impact for assists were members of the Jazz. Gordon Hayward was found to have been short changed more than 28 assists over the season, a gap that would have seen him move up to 36th from 46th overall in the category.Chris Paul of the Los Angeles Clippers, meanwhile, was credited with almost 35 assists more than the study suggests he deserved.Van Bommel said the systematic bias could also impact the still growing analytics world, which often relies on in arena scorekeepers."A lot of advanced statistics still use the box score as input," said van Bommel, adding: "Fan and media perception is also heavily influenced."Bornn, who was van Bommel's supervisor at SFU, was recently hired by the Sacramento Kings as vice president of strategy and analytics.
