Jaylen Brown says he has to “reverse engineer” his brain after being programmed to hate Philadelphia for 10 years

Jaylen Brown hopped on a Twitch stream after being traded from the Celtics to the Sixers in the Paul George blockbuster and said what every single person involved in this deal already knew, which is that spending a decade in Boston programmed him to despise everything about Philadelphia and the process of flipping that switch in his brain from “fuck the Process” to “I am the Process” is going to take some time before the season starts.

Jaylen Brown needs to reverse engineer his brain

Jaylen Brown being real about the move to the Sixers:

“For the last 10 years, I’ve been programmed to hate Philadelphia,” Brown said. “From the history of the rivalry to the playoff battles, all of the above. I’ve been programmed to be like, man, fuck the Process. But now I have to reverse-engineer, that’s the part that’s going to take some time.”

I respect the honesty because Jaylen Brown could have gone on social media and done the generic “excited for a new chapter” press release language that every traded player in the history of professional sports defaults to when they don’t want to say anything real.

Instead the man went on Twitch and told the world that he’s spent a decade hating the city he’s about to play for and needs to rewire his entire competitive identity before October because the guy who was screaming “fuck the Process” during playoff series against the Sixers is now one of the most important pieces of the Process moving forward.

That’s the kind of raw, unfiltered honesty that Philadelphia fans are going to love once they get past the initial weirdness of hearing a former Celtic talk about hating their city because this fanbase respects people who say what they actually think instead of hiding behind corporate talking points.

We hear you, Jaylen Brown

Honestly, the feeling was mutual because every Sixers fan alive has spent the last decade hating Jaylen Brown’s guts every time he torched the Sixers in a playoff series or hit a dagger three at Wells Fargo Center while wearing that ugly green jersey.

The Celtics-Sixers rivalry produced some of the most intense and personal basketball the Eastern Conference has seen over the last 10 years and Brown was in the middle of all of it as one of the faces of the franchise that Sixers fans viewed as the primary obstacle between Philadelphia and a Conference Finals appearance.

Now that guy is wearing a Sixers uniform and the fans who were cursing his name six months ago are going to be cheering every time he dunks on someone at Wells Fargo Center because professional sports are the only industry on earth where your mortal enemy can become your favorite player overnight through the magic of a trade call.

Jaylen Brown Coming Off a Career-Best Season Makes This Even Bigger

Brown averaged 28.7 points, 6.9 rebounds, and 5.1 assists last season, which are career highs across the board from a 29-year-old who is entering the third year of his five-year, $285 million contract and was the 2024 NBA Finals MVP just two years ago when he led the Celtics to a championship that Sixers fans had to watch from their couches while Boston celebrated on their home floor.

The man is a five-time All-Star in his absolute prime who was traded to the Sixers because the Celtics apparently decided that Paul George’s declining production and some draft picks were worth more than the guy who won them a Finals MVP, which is either the worst trade in recent Celtics history or a salary dump disguised as a basketball move that Boston is going to regret for the next three years while Brown is averaging 28 a night in a Sixers uniform.

Jaylen Brown on the Sixers gives Gansey something that no previous front office regime in the Process era was able to acquire, which is a legitimate two-way wing who can score 28 points a night, defend the opposing team’s best perimeter player, and provide the kind of playoff-tested star power that this roster has been missing since Jimmy Butler left in 2019.

The Sixers have had Embiid and they’ve had guys around Embiid, but they’ve never had a player with Brown’s combination of scoring ability, defensive versatility, and championship experience alongside Embiid, and the possibility of what that pairing could look like with Maxey running the offense and Edgecombe developing into a lockdown wing defender is enough to make you forget that Brown spent 10 years hating Philadelphia before he got here.

The “Lack of Respect” Comment About the Celtics Is Telling

Jaylen Brown mentioned during the Twitch stream that the trade came with mixed emotions and a sense that the Celtics showed “a lack of respect” during the process of moving him, which is the kind of comment that tells you the relationship between Brown and the Boston front office had deteriorated to the point where both sides were ready to move on even if neither wanted to admit it publicly.

When a player who won you a Finals MVP two years ago says the organization disrespected him during the trade process, you know there’s more to the story than what’s being reported and the feelings behind that comment are going to fuel Brown’s motivation to prove Boston made a mistake every single time the Sixers play the Celtics next season.

Philadelphia is the perfect landing spot for a player who feels disrespected by his former team because this city runs on the energy of players who have something to prove and use perceived slights as motivation to perform at a higher level than anyone thought possible.

Jaylen Brown feeling like Boston didn’t respect him during the trade is going to translate into a level of intensity and competitive anger that Sixers fans are going to feed off of every night at Wells Fargo Center because there is no fanbase in professional sports that embraces the “us against the world” mentality more than Philadelphia.

Brown arriving with a chip on his shoulder from the Celtics is exactly the kind of energy this franchise needs after years of passive, corporate basketball that produced zero Conference Finals appearances.

The Roster Around Jaylen Brown Is Built for Something Special

Maxey, Edgecombe, Brown, Embiid, and now Simons off the bench with Philon developing behind them gives the Sixers a roster that has legitimate star power at multiple positions for the first time since the peak of the Embiid-Simmons era, and the difference between this version and that version is that Brown can actually shoot from three at a 36 percent clip while scoring 28 a night, which solves the spacing problem that destroyed the Simmons pairing with Embiid and gives the Sixers a perimeter threat that opposing defenses have to respect in a way they never had to respect Simmons standing in the dunker spot refusing to shoot.

Jaylen Brown said his “brain is doing a 360 right now” and he needs time to reverse-engineer the hatred of Philadelphia that was built into his competitive DNA over a decade in Boston, and honestly the fact that he’s being this open about the adjustment period tells you he takes the transition seriously enough to acknowledge that it’s going to require real mental work rather than just showing up and pretending the rivalry never existed.

The fans are going to meet him halfway because Sixers fans don’t need you to love Philadelphia from day one, they need you to compete with everything you have and let the relationship develop through shared battles and big moments, and a player with Brown’s talent and competitiveness is going to produce enough of those moments that the decade of hatred will be forgotten by Christmas.

Rich Paul said LeBron’s attention is on the Sixers because “everything changed” with the Brown trade, and he’s right because the addition of a 28-point scorer and Finals MVP to a roster that already has Maxey and Embiid transforms the Sixers from a team hoping to make the second round into a team that can legitimately compete with the Knicks and the Heat for Eastern Conference supremacy.

Rich Paul had a lot to say about the LeBron James, the Sixers, and how the Jaylen Brown trade changed everything >>

If LeBron comes too, the Sixers go from contender to favorite overnight, but even without James the Brown-Maxey-Embiid-Edgecombe core is the most talented group the Sixers have put on the floor since the Process began.

Jaylen Brown spent 10 years hating Philadelphia and now he’s going to spend the next three years playing for Philadelphia, and the transformation from enemy to ally is going to be one of the best storylines in the NBA next season because the man isn’t pretending the rivalry didn’t exist or that the hatred wasn’t real.

He’s acknowledging it, processing it publicly, and committing to rewiring his brain before October because that’s what professionals do when the situation changes and the jersey changes and the only thing left to do is compete for the people who are cheering for you now instead of the ones who used to.
