Vegas Insider ran the numbers and these are their projected regular season wins for the 2015-16 NBA season. You should check out their article for a more detailed look at the process. We also took their projected data and lined it up against last year's regular season wins for each team (see bottom graphic).
• The Spurs have the highest (62.5 games) and the 76ers have the lowest (17.5) over/under.
• The Trail Blazers are expected to see the biggest drop. Last year Portland finished with 51 regular season wins, but Vegas Insider has this year's over/under at 26.5
• It's no real surprise that the Thunder are supposed to make the biggest jump after finishing 2014-15 with a disappointing 45 wins. Vegas Insider has OKC's over/under at 59.5.
• Vegas Insider appears to think that the Hawks 2014-15 "dream season" was simply that. The over/under for Atlanta is 46.5.
