The NBA Final Four consists of four franchises long overdue for a champagne celebration.

The Phoenix Suns, the Los Angeles Clippers, the Milwaukee Bucks and the Atlanta Hawks have been on the outside looking in for decades.

The Suns and Clippers have never been NBA champions. Milwaukee hasn’t prevailed since 1971, while the Hawks have been searching for the right answer since 1958.

That leaves many of the game’s top players on the sidelines. No LeBron James, Steph Curry, Kevin Durant. No Lakers, Celtics or Warriors.

It’s time for change. On the upswing, a long wait will come to an end for one of the NBA’s “have nots.”
