The Cleveland Cavaliers are one of the best teams in the NBA, as evidenced by their record last season. Going 51-31 and being the fourth seed in the Eastern Conference is not something every team can boast about, especially teams that are as young as Cleveland.
The problem was in the playoffs, as the Cavaliers practically collapsed, and only won a single game against the New York Knicks. Technically, it was an upset, considering the Knicks were the lower seed entering the series. Considering how Cleveland played during the series, it looked like the Cavaliers were closer to a play-in team, more so than a sturdy top-seeded team.
