The duos are ranked here from most likely to win an NBA championship to most likely to end up broken, bickering and Bernie Madoff-like:

1. Kawhi Leonard-Paul George, Los Angeles Clippers: They are in their prime, they are surrounded by wonderful complementary parts and they have a fine coach, Doc Rivers. What could go wrong?

Well, everything.

Both are still somewhat youthful – Leonard is 28, George 29 – but both might have trouble staying on the court. In eight NBA seasons, Leonard has played 66 or fewer games six times; George, meanwhile, fractured his right leg to miss almost all of 2014-15, and he missed the first 11 games this season after shoulder surgery.

Heck, load management issues alone might keep Leonard out of Games 1, 3 and 6 in a seven-game NBA Finals.

2. LeBron James-Anthony Davis, Los Angeles Lakers: These are inarguably two of the best all-around players in the NBA, unless you want to argue the point.

James seems indestructible, except he'll turn 35 next month, he's in his 17th NBA season and he takes more hits than Tom Brady. The Lakers could not survive a prolonged period in which James is sidelined.

Davis, who never has played more than 75 games in a season, just spent seven years in New Orleans in witness protection; he can't wait for the postseason, since he only got there twice with the Pelicans.

3. James Harden-Russell Westbrook, Houston Rockets: This feels like a sporting Manhattan Project, except instead of secrecy, this race to make the first atomic bomb is played out in large arenas three nights a week. Harden (uranium) and Westbrook (plutonium), are durable ball hogs and wondrous to watch. But if you told either former MVP to play 48 minutes and take 50 shots, either might reply, "Why not 60 shots?"

4. Kyrie Irving-Kevin Durant, Brooklyn Nets: Too big to fail? No. Too fanciful to succeed. This is a more guaranteed bust than the next Charlie Sheen sitcom. Irving and Durant keep seeking new homes to show the true measure of their talent. But they are as temperamental as talented, and Durant – out this entire season with a torn ACL – might be a step-too-slow diva when he returns.

Anyhow, ballyhooed pairings are not guaranteed to thrive. For example:

Richard Nixon-Spiro Agnew: This simply did not end well for all parties concerned.

Sears-Kmart: The only thing that would've made this retail merger worse is if Radio Shack were involved.

Julius Caesar and Cleopatra: Frankly, I think they were using each other.

Gilligan and the Skipper: Despite better WiFi and more precise GPS than ever, these bozos are still deserted on that island.

Bonnie and Clyde: I understand getting out of the house on occasion to break the same old same old, but these lovebirds were just a bit too edgy for their own good.

America Online-Time Warner: I have earned a paycheck from both companies, and I am here to tell you – this was a nightmare alliance made in purgatory and destined for hell.

Romeo and Juliet: If they had eloped – and I recommend eloping, particularly on your second or third go-around – I believe a life or two would've been spared.

Thelma & Louise: And they say women are smarter.

On the other hand, kudos to Wile E. Coyote and the Road Runner for always understanding their roles.
