Once Durant made his intentions known, what the team has done is probably as good as it gets for this season. Probably could read definitely. The difficult thing will be to measure next season (unless the team do the seemingly impossible and get to the finals by beating the Cavs) as the next step is the finals and/or a championship.
Even with the number 1 pick and what the team has achieved (in the weaker East conference), all the assets and potential, it is still difficult to see how you beat the Cavs and GSW.
That said, the team should be celebrated, whatever happens for the rest of this series, for doing so well this season.
