Forget the phrase 'threw him under the bus' and focus more on how Simmons felt after the series. Is he soft? Sure, but it's up to a franchise to coddle their star player. That's just how it is. We also don't know what was said behind the scenes. We do know the media's take on what Doc and Embiid had to say at the time, and bdm seems to have brushed right over that part.
From sources close to Simmons:
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.
I get it, Simmons should be tougher and deal with criticism better, but he isn't and he didn't. The fact that PHI seemed to make the problem worse by painting Simmons in a negative light throughout the process certainly didn't help.
And my main point all along is if they had just traded him - like every team in the history of the world has done - there would be no drama. Ben would be tearing it up with another team and PHI would be doing even better because they would have gotten a high level asset (or assets) to play at the beginning of the season. PHI is to blame in my opinion - they really blew it with one of their franchise players and needed to do a better job at making things better.
Simmons take on the Toronto series is an idiotic PR move. Embiid was sick for most of that series. Even so while Embiid shot poorly during the series, the Sixers were something like +89 when Embiid was on court. In the 7th game, the Sixers were +10 in the 45 minutes Embiid played and -12 in the 3 minutes he was off court. Embiid and to a lesser extent Butler carried the Sixers that series.
As for Simmons being a franchise player, ROTFLOL. Setting aside his skillset limitations, he doesn't have the mentality or work ethic to be a franchise player. The Sixers mistake was spending so long coddling and trying to accommodate Simmons.
I'm not saying that Simmons' reasoning is valid, but those are his perceived feelings and PHI should have done what they could to make him feel better, rather than push him into most hated player in the NBA territory. You can view a 25 y/o 3X All-Star and All-NBA player as not a franchise player, but those are very solid accolades for such a young player - especially since he contributed to winning.
The thing is, PHI can't have it both ways. If they view him as a franchise player, they should be coddling the hell out of him. If they don't, they should have traded him this past summer. I don't really have a horse in this race either way - I've never been a huge Simmons fan or anything - I just think it's PHI who totally screwed this up. And that's not surprising because they always screw everything up.
Personally, I think it's too early to judge Philly, while it's easy to judge Simmons at this time. So that's why Simmons gets a lot of hate now.
If Philly eventually turns Simmons into Harden, Lillard, Beal or some other star that wasn't originally being offered, then they come off looking like geniuses. If they settle for the same or a worse deal than has reportedly already been offered after wasting a year of Embiid's prime, then they'll look like idiots and deserve blame. So the jury is still out on Philly.
And I think you're overestimating how quickly teams react to superstar's trade demands.
In the 2004 offseason, Vince Carter demanded a trade from Toronto, but they didn't trade him until 21 games into the season.
In the 2007 offseason, Kobe Bryant said he wanted to be traded from the Lakers. Unfortunately for the C's, the Lakers didn't listen.
In the 2010 offseason, Carmelo Anthony requested a trade from the Nuggets, and wasn't traded until a week before the trade deadline.
Before the 2012 season started, Dwight Howard demanded a trade from the Magic, the Magic instead got him to withdraw his trade request and kept him for the whole season and didn't trade him until the next offseason.
Before the 2019 season, Jimmy Butler demanded a trade from the Wolves, but they didn't trade him until 13 games into the season.
In the middle of 2019 season, Anthony Davis demanded a trade and had to wait 6 months and half a season for that to happen.
Before the 2021 season started, James Harden requested a trade, but still had to wait 2 months and 9 games into the season before it happened.
I don't have any problem with Philly waiting for the right deal like many other teams with disgruntled superstars have done in the past.
