Power Rankings: Best, worst cases for all 30 teams — and where each could stumble

Can the Golden State Warriors return to the club? Victories will LeBron James add to the Los Angeles Lakers’ tally? And where would they stumble?
We’re projecting all 30 teams’ finest — and worst-case scenarios and where every could hit bumps in the street throughout the 2018-19 season.
Our board — a set of more than 40 reporters, insiders and editors — will be looking ahead to this season with a new variant of NBA Power Rankings. Voters were asked to pick the better team heading into this year in a run of head-to-head matchups comprising tens of thousands of votes.
Notice: Our best-case/worst-case situations and month-by-month win percentages were created using ESPN’s Basketball Power Index. For best-case/worst-case situations, we used outcomes that had a three percent or higher chance of occurring, based on BPI projections of this 2018-19 season.
