Ben Simmons' complete list of grievances with the Philadelphia 76ers is no doubt long. Those he and his camp decided to share publicly with ESPN's Ramona Shelburne, though, don't exactly portray Simmons' superstar teammate and current head coach in as negative a light as they think.

In a sprawling feature story on the drama continuing to engulf Simmons and the Sixers as the February 10th trade deadline approaches, Shelburne details the three-time All-Star's sources of frustration with Joel Embiid and Doc Rivers.

According to sources close to Simmons, he's upset that Embiid seemed to blame him for last season's playoff loss, when Simmons did not blame Embiid for Embiid's poor showing in the playoffs against the Toronto Raptors in 2019. He's frustrated that Rivers didn't come to see him while he was training in Los Angeles last summer.

Simmons doesn't dispute that he didn't reply when Rivers texted and called him several times over the summer asking to see him. But in hindsight, Simmons feels Rivers and the Sixers could've done more, like show up at a well-known gym in the San Fernando Valley where he was training.

Embiid indeed threw Simmons under the bus after last season's stunning defeat to the Atlanta Hawks in Game 7 of the Eastern Conference Semifinals, noting the tenor of the game changed entirely when Simmons infamously passed up a would-be dunk in crunch-time. But the notion that Embiid bears nearly as much responsibility for the Sixers' 2019 playoff defeat to the Toronto Raptors as Simmons does last spring's loss to the Hawks doesn't come close to passing first blush.

Case in point: Philadelphia was +90 in the 237 minutes Embiid was on the floor against the eventual-champion Raptors, and a comical -109 in the 99 minutes he rested, per NBA.com/stats. Embiid's efficiency and per-game numbers fell far below his dominant standard, in large part due to stellar individual defense from Marc Gasol, but there's no denying he was by far the Sixers' most impactful player in that series.

Only Simmons and Rivers know the particulars of their communication—or more accurately, lack thereof—between the end of last season and tipoff of 2021-22. Still, the expectation that Rivers was supposed to trail Simmons on the Southern California open-gym circuit, evidently against the latter's wishes, is foolish.

Even Simmons detractors, though, can't dispute that Philadelphia began this rigmarole last winter, when the league's worst open secret was Daryl Morey's desire to trade him for James Harden. That turn of events reportedly still nags at Simmons, especially as it's culminated in the Sixers fining him for being away from the team this season while he deals with mental health issues.

Still looming over this whole ordeal? The prospect of Philly going after Harden again via trade or free agency this summer, a rumor that's picked up steam as the deadline draws closer.

He's also skeptical, sources close to him say, of Sixers president of basketball operations Daryl Morey's willingness to trade him because of his previous pursuit of Harden — who can become a free agent this summer. Simmons would be the best player the Sixers would send in any theoretical trade. And he's upset that the organization is fining him so heavily after he raised mental health as an issue upon his return.

None of this intel changes what's been obvious for weeks. The SIxerscould very well trade Simmons before February 10th, but it almost certainly won't be for anything less than an All-Star caliber player. And if he's on the roster post-deadline, expect chatter about Harden's potential future in Philly to be the talk of the offseaosn.
