If both NBA conference finals end in sweeps, there will be a week and half with no basketball. Even with the inexplicable two days free of basketball coming later this week, the final conference finals game would take place May 25; the NBA Finals don't start until June 3.
Even if a series goes five games, there will be a week off between the end of the league's semifinals and the championship series. This is really a failure on the part of the NBA. Come on guys, keep things going.
