Congratulations to the San Antonio Spurs for their second-round series victory over the Houston Rockets, and good luck to the Boston Celtics as they attempt to close out the Washington Wizards.

You're both on the verge of Armageddon.

How else can you describe the slaughter that awaits each conference's also-ran in the semifinals of the NBA playoffs? The Cleveland Cavaliers and Golden State Warriors are primed to destroy their supposed competition on the way to an NBA Finals rubber match.

This was the inevitable result of the 2016-17 season, and it's finally here. With just a few more games, we'll get to see LeBron James try to vanquish the superteam built specifically to destroy his throne.

And to anyone sick of the NBA's lack of parity, we have both good and bad news.

The bad news is things aren't going to change any time in the immediate future. Barring a catastrophic injury (or two), the Cavaliers and Warriors are destined to go toe-to-toe for a fourth straight Finals next season.

But there is a light on the horizon, faint as it might be. This era of two teams crushing the rest of the NBA could come to an end sooner than you think.

Let's start with the Cavaliers and the seemingly immortal LeBron James.

I'm not here to bury The King, or even to tell you he's about to enter some sort of decline. He's the greatest player on the planet, potentially the best ever, and he remains at the top of his game.

At some point, though, LeBron is going to slow down. (We even have five ways you'll be able to tell once he finally does.) He'll still be the best player in the NBA, but the margin between him and the field will narrow.

And if he can't play like the greatest of all time, Cleveland is going to find itself in trouble, relatively speaking. The Cavaliers' entire game plan at this point is predicated on finding over-the-hill veterans who want to chase a ring, guys LeBron can elevate back to some level of NBA productivity.
