According to ABC News, the Golden State Warriors currently have a 43 percent chance of actually attaining 73 wins this season. On the flip side, they do have a 68 percent chance of getting at least 72 wins, though. So, there’s a, basically, two-in-three chance that the team at least ties the 1995-96 Chicago Bulls for most wins in a season.

If you want to put it into fun terms, the Warriors have nearly the same chance of winning 72 games this season as DeAndre Jordan does of making a shot.
