Hoopsalytics Quotes:

Bill:  “Basketball is really data rich . . every game that we score, there’s between 500 and 700 events. There’s so much information in there that people aren’t tapping into, especially for some of the coaches that may not even have an assistant.”

Bill:  “Defense is really hard to measure because we have steals, deflections, rebounds, and that’s basically it. And that doesn’t really tell the whole story . . So one of the stats that we like . . is a defensive points per possession. It basically measures how well the other team scores when a particular player is on the floor.”

Bill:  “One of the other things you can track with shots is how contested they are . . so, it turns out most of the reason that these inside out shots are working better is because you’re getting more uncontested looks on the shots, especially on offensive rebounds, where everybody comes in and you kick it out and somebody’s wide open.”

Mike:  “One of our pro teams wanted to track a small advantage turning into a big advantage. So, their idea was to track every time that the ball touched the paint, whether on the dribble or the pass, and then what happened after that, whether it was an uncontested or a contested three or long two, whatever the result was. Paint touches is a really great indicator of how your offense can perform with or without the paint touch.”

Bill:  “We know which five players are on the floor every second of the game. So, we can measure the points per possession . . both offensively and defensively. And then the net offense minus defense, so you can find your best two-way lineups.”

Mike:  “With Hoopsalytics, you can focus on, for example, your best five defensive lineup in the fourth quarter, or the last five minutes of a game . . being able to isolate on a particular part of the game to see who your best players are is a tool that I know that a lot of coaches that I work with use.”

Bill:  “One of the game summary stats that we provide you is we show you how many live ball turnovers for each team and what the points per possession were on the live ball versus the dead ball turnovers.”

Mike:  “Hustle plays and their score was a competitive thing amongst the team . . If you present it to the kids in a competitive way, they embrace it. Floor dives, deflections, taking a charge, all the dirty work that most kids generally don’t do or don’t like to do, gets rewarded and helps get playing time and that’s always a very motivating factor.”

Mike:  “Especially in a team film session . . you can say, ‘Look, this is not a good shot for you. Don’t take this shot anymore. I’d rather you take a step back and shoot the three. This way we can get some points value, perhaps on the long rebound and putbacks, but also on effective field goal.’ The shot charts are a big help in illuminating the players to the statistics.”
