The NBA is pushing toward changes to the draft lottery system by next season but is facing a strong objection from the Philadelphia 76ers, the franchise that could suffer the most from it, multiple sources told ESPN.com. Lottery-reform measures were introduced earlier this month at league meetings in Las Vegas, and the NBA Board of Governors could vote changes into place at its preseason meeting in October. Although there are several facets and the proposals haven't been finalized, the goal of commissioner Adam Silver is to balance out the lottery odds so the worst team or teams wouldn't have the highest chances of landing the top pick, sources said. Currently, the team with the worst record has a 25 percent chance of landing the top pick and the team with the fifth-worst record has an 8.8 percent chance of winning it. In a new format, the bottom five or six teams could have an equal chance. Grantland's Zach Lowe reported earlier this month on the NBA's proposed changes, which are essentially an attempt to squeeze the lottery odds at either extreme toward a more balanced system in which all 14 teams have a relatively similar chance at the no. 1 pick. Although the NBA likely would not frame the changes this way, they could be seen as an anti-tanking measure, as teams with the worst records might not earn significantly higher lottery odds.
