The 29 NBA teams that are not the Golden State Warriors should brace themselves: Their odds of knocking off Golden State are even longer this season. The Warriors have a 57.9 percent chance to repeat as NBA champs, according to preseason numbers from ESPN's Basketball Power Index (BPI). That makes them even heavier favorites than they were this time last year, when they were still the likeliest team to win it all (52.4 percent) by an overwhelming margin.
BPI is a forward-looking model that predicts the strength of each team on offense, defense and altogether.
