    How do books know NBA lines so good?
    They are always spot on. Very odd. For example the Spurs just covered the first half

    Lots more data collected and able to parse... I imagine they are running lots of data centers with artificial intelligence to pick the lines and then probably review them by experts. That is my guess at least.

        Well some lines are intentionally off that is where artificial intelligence comes in. It can also pick whether people will bet largely on a bigger favorite spread then a dog. It can analyze betting history of the public and where money is going. For example I’m guessing most people took New Orleans or Charlotte tonight. I don’t know that for sure but the line could be set even larger on the public convincing them it’s going to be a blow out. Also, same can be done with setting a favorite lower to intentionally make it look fishy to get people to bet the dog. Even if the intelligence thinks differently about what the games really will be. I think this is why sometimes team totals don’t really match spread or they don’t match game over under. Anyhow that’s my 2 cents on it

                  Let's face it, oddsmakers know their stuff.

                  But.....Could it be that they get so many lines close to the final result, simply because they crank out so many day after day?

                    on an average day with an average number of games, it's all about the averages.

                      NBA numbers are the most solid of any sport which is why I quit toying with it

                      They have consistent data month in and month out and also have the public sentiment down to a science

                      They have the best saber number guys in the business firing off these numbers and over the long term it's just not worth banging my head each night trying to get my 2 or 3% ROI out of it

                      Even that hoop head that designed the computer program "Ewing" has to keep adjusting and from what I understand is down quite a bit so far this year

                      Only way to find a number that is off is to know something they don't like an unknown injury or a team that isn't going to give 100% which again is few and far between

                            Good luck finding out about an "unknown injury" before the books. They're on top of that stuff, guaranteed. Agree with the second one though, gotta isolate when teams actually will/won't show up, and more importantly, find such spots the books have not adjusted the spread for accurately. NBA betting is all situational, 100%.

                              NBA is worst sport to bet by far as the lines are too sharp. Too many games, injuries, players and teams don't give a shit. college basketball similar for big conferences until March Madness when the betting volume picks up and public can swing lines. At least in NFL and College Football you can grab key numbers / spots if you bet early enough

                                  It's not impossible but the books are pretty scary when it comes to predicting the lines. For e.g. for Totals in 2015 -2016 the actual total points average was 205.92; the books total line avg was 205.62; so a difference of 0.3 for 1230 games. This season so far the avg books line is at 211.22 while the actual score avg is 211.06, a diff of 0.16

                                  That's the type margin we have to work with...

                                    Bullshit. The point spread on the NBA is off more than 7pts in half the games. You think that's accurate?! "They" don't know, and that's what makes it so intruiging.

                                      When I first started, many moons ago, I used to think the odds were way off at the start of the season and got sharper as the season progressed with (as posters above say) the statisticians going to work. Then I did a test and found the accuracy from one part of the season to the next is only the slightest bit more on point.

                                                The clock operator at Staples started the clock too soon on the inbound play for Washington. Beal's shot would of been awfully close.

                                                            I had Spurs first half last night and it was a push for me.

                                                            It was an awesome push though.
