The Nets are playing well right now, but there are a bunch of teams worse than them in the standings who should end the season with more wins than Brooklyn.
Minnesota, Denver, Washington, Dallas should all finish the season with more wins than Brooklyn. An argument can be made that Miami, New Orleans, and Sacramento could end the season better than Brooklyn.
They are playing really hard, which means that they will get more wins than their talent indicates, but I still think they aren't very good.
