With that out of the way, who will challenge the Warriors next season besides the Cleveland Cavaliers, who are listed as the +400 second choice? Cleveland is hoping to return to the NBA Finals for a fourth straight championship matchup with Golden State.

The Cavaliers might not have much competition in the Eastern Conference, but the Boston Celtics are undoubtedly the team with the most potential to upset them. The Celtics signed prized free agent Gordon Hayward away from the Utah Jazz and Miami Heat on Tuesday, improving their odds to win their 18th NBA title next year.
