James Harden has left Brooklyn Nets for Philadelphia 76ers with Ben Simmons heading in the opposite direction in the biggest deal on the NBA's trade deadline day.
The Sixers are 7/1 to win the NBA Championship outright and the Nets can be backed at 17/4.
Harden only made the move to Brooklyn last January to form a big three with Kevin Durant and Kyrie Irving but the trio were never really able to form a strong unit.
Harden and Irving were both injured during last year's playoffs as Brooklyn fell short in their bid for the championship, and this season the trio played just two games together as Irving had only just returned to action.
There had been rumours circling that a deal for Harden and Simmons could happen in the days leading up to the deadline, and Brooklyn opted to sanction the deal as the 2018 MVP could have left as a free agent at the end of the campaign.
Simmons hasn't played for Philadelphia this season after requesting a trade during the summer. The All-Star guard should improve Brooklyn's defence, while Harden makes the Sixers a far more impressive team offensively.
As well as Simmons, Brooklyn have also received guard Seth Curry, center Andre Drummond and two future first-round draft picks.
The Nets have sent Paul Millsap to Philadelphia as part of the deal.
Losing Curry and Drummond does impact the Sixers in terms of squad depth but pairing Harden with Joel Embiid gives them a genuine shot at challenging for the championship, while Brooklyn will feel they still remain serious contenders despite breaking up their big three.
