The Oklahoma City Thunder went through with the final move that pushes them into a full-blown rebuild.
Here are the biggest takeaways from what was, yet, another blockbuster trade in the NBA:
Both stars make the most damage with the ball in their hands but so did Harden and Paul. That combination was a game away from defeating the Golden State Warriors in the Western Conference Finals just a year ago. LeBron James and Kyrie Irving weren't the perfect fit with the Cleveland Cavaliers, but their elite talent got them a championship in 2016.
Mike D'Antoni will have his hands full making it work, but the two jelled enough in Oklahoma City to help get the Thunder to an appearance in the NBA Finals in 2012.
Star power > fit.
Houston did this with Harden and Paul two years ago, but with the diminishing relationship between the two and Paul's health breaking down, the Rockets needed another Robin to Harden's Batmam to keep up in the arms race.
Westbrook and Harden will now compete with multiple elite tandems in the Western Conference that includes LeBron and Anthony Davis with the Los Angeles Lakers, Kawhi Leonard and Paul George with the Los Angeles Clippers, and the splash brothers in Golden State when Klay Thompson returns to full health.
That doesn't include the young combination of Jamal Murray and Nikola Jokic with the Denver Nuggets, the overall complete roster of the Utah Jazz, or any of the star power in the Eastern Conference. That talent in the East includes Kevin Durant (Brooklyn Nets), Giannis Antetokounmpo (Milwaukee Bucks), and Joel Embiid (Philadelphia 76ers).
However, the fact that Presti could not find the coach or supporting cast to give his stars a shot at the title every year should be seen as a massive failure. The lack of shooters and a growing frustration with Billy Donovan is believed to be a part in Durant, George, and Westbrook's displeasure with the franchise.
Donovan lacked any creativity on the offensive side of the court and the lack of any shooters who could hit a three-pointer north of 35% didn't help.
Thunder fans will now be left to think about what could have been.
