Philadelphia 76ers point guard Ben Simmons is one of the big names who are highly expected to be traded during the 2021-22 NBA season. As the 2022 NBA trade deadline approaches, the Sixers are becoming more aggressive in finding their disgruntled superstar a new home. As of now, they aren't only aiming to move Simmons, but they are also attempting to trade another starter.According to Sam Amick of The Athletic, the Sixers have expressed willingness to include Tobias Harris in the potential trade packages involving Simmons.Sixers Engaged In Trade Negotiation With KingsSo far, the Sixers have already discussed trades involving Simmons and Harris with multiple NBA teams. As Amick noted, one of the trade partners for the Sixers in the deal featuring Simmons and Harris is the Sacramento Kings. The Kings have been interested in adding Simmons to their roster since the 2021 NBA offseason.With the team likely heading into another huge disappointment this season, rumors are circulating that the Kings are planning to tear their roster down and undergo another rebuild.Proposed Three-Team TradeAmick didn't give any specific details regarding the trade negotiation between the Sixers and the Kings. However, some fans have started to create their own prediction regarding what the potential deal between the two teams could look like. In a recent article, Corey Rausch of Fansided's Hoops Habit came up with a hypothetical three-team trade idea that would send Simmons and Harris to the Kings before the 2022 NBA trade deadline.In the proposed trade scenario, the Kings would get Simmons, Harris, Avery Bradley, and Talen Horton-Tucker, the Sixers would receive De'Aaron Fox, Harrison Barnes, Kendrick Nunn, and Wayne Ellington, while the Los Angeles Lakers would obtain Buddy Hield, Charles Bassey, and Paul Reed.Kings Overhaul Roster Around Tyrese Haliburton & Davion MitchellThe proposed blockbuster deal would make sense for the Kings if they no longer believe in Fox as the centerpiece of the team. As Rausch noted, the suggested trade allow the Kings to shift to building around Tyrese Haliburton and Davion Mitchell."Ben Simmons comes in to play the Draymond Green role that he was born to play, cementing this team as a dynamic defensive starting five," Rausch wrote. "Tobias Harris adds scoring punch with hopes that the change of scenery rejuvenates him. Talen Horton-Tucker has some intrigue and can be brought along slowly off the bench with significantly less pressure than he currently faces."Why Sixers & Lakers Would Make The TradeIf the trade would push through before the 2022 NBA trade deadline, it wouldn't only benefit the Kings, but also the Sixers and the Lakers. For the Sixers, they would be receiving an immediate replacement for Simmons and Harris in the starting lineup in Fox and Barnes, while adding two solid veteran role players in Ellington and Nunn.For the Lakers, the suggested trade would allow them to correct the mistake that they did in the last offseason when chose Russell Westbrook over Hield. Hield would give the Lakers the much-needed improvement in floor-spacing around their core of LeBron James, Anthony Davis, and Westbrook.
