Who are the NBA league's best teams now?

Free agency saw Kevin Durant and Kyrie Irving team up in Brooklyn, D'Angelo Russell join the Splash Brothers, Jimmy Butler take his talents to South Beach, and Tobias Harris and Kristaps Porzingis sign max deals with Philly and Dallas, respectively. The league has changed seemingly, and we're here to make sense of where all teams stand heading into a highly anticipated 2019-20 season. All NBA datas collected from iSpots API.

1. Milwaukee Bucks

While the fabric of the Eastern Conference has changed drastically in recent weeks, the Bucks' core has stayed largely the same. The team re-signed starters Khris Middleton and Brook Lopez as well as key reserve George Hill. What set the team apart last season was its deep bench. Will the acquisitions of Robin Lopez and Wesley Matthews be enough to make up for the departures of Malcolm Brogdon, Tony Snell and Nikola Mirotic? A strong bench to support Giannis Antetokounmpo is essential for Milwaukee to make it out of the East finals.

2. Denver Nuggets

While the rest of the NBA world went wild, the Nuggets made a few moves along the edges but quietly had one of the best summers of anyone. Adding Jerami Grant is one of the most underrated moves of the offseason, and they effectively are adding 2018 No. 14 overall pick Michael Porter Jr., who sat out the entire season with back issues. Assuming progression from their young rising stars, the Nuggets are firmly a favorite in the West.

3. LA Clippers

After a year of rumors of quietly recruiting Kawhi Leonard, the Clippers landed the mysterious forward after what might have been the most intrigue-filled week in free agency in recent memory. Shocking the Lakers, the Raptors and the entire NBA, the Clippers persuaded Leonard to become a Clipper by stealthily working a trade for Paul George. Though the blockbuster move cost a historic haul of five first-round picks, two first-round-pick swaps and Shai Gilgeous-Alexander and Danilo Gallinari, the Clippers are now instant title contenders. Leonard and George should fit in seamlessly with a gritty supporting cast and budding Clipper culture built on a low-ego, team-first mentality. Doc Rivers' defense could be the nastiest in the NBA with Leonard, George and Patrick Beverley forming a perimeter wall. Rivers has the best second-unit combo in Lou Williams and Montrezl Harrell, and role players such as JaMychal Green, Maurice Harkless and Landry Shamet might make the Clippers the best team in not just Staples Center this season but perhaps in the entire league.

4. Philadelphia 76ers

After coming within four bounces of beating the Raptors, falling with a devastating loss at the buzzer in Game 7 of the Eastern Conference semifinals, the 76ers went out and made some dramatic moves this summer: re-signing Tobias Harris to a five-year, $180 million deal; executing a sign-and-trade with the Miami Heat, sending Jimmy Butler there in exchange for Josh Richardson; and signing Al Horford away from the Boston Celtics with a four-year, $113 million contract. Now, thanks to Leonard leaving Toronto and the rest of the East contenders either standing still or taking a step backward, Philadelphia seems to be the favorite to emerge from the East and reach the NBA Finals for the first time since Allen Iverson led the Sixers there in 2001.

5. Houston Rockets

The Rockets rolled the dice by reuniting Russell Westbrook with James Harden, particularly considering the hefty price of the lightly protected 2024 and 2026 first-round picks they sent to Oklahoma City along with Chris Paul. "It's risky for sure, but I believe the upside is greater than with CP," a team source said. Westbrook's ball dominance and poor 3-point shooting present fit concerns, but Harden pushed hard for the trade, which the Rockets hope will allow them to be legitimate contenders through The Beard's prime, and their window was closing because of the 34-year-old Paul's physical decline.
