As I stepped into the O2 Arena on that crisp Thursday night in 2025, I couldn't help but feel the weight of history surrounding me. The Boston Celtics and Philadelphia 76ers - two franchises that have been battling since the very dawn of professional basketball - were about to renew their historic rivalry on international soil. It's mind-blowing to think that these two teams have been going at it since 1946, when the NBA (then called the Basketball Association of America) first tipped off with just eight teams total.

Back in those early days, the league was so small that these two teams faced each other constantly. I mean, picture this: only eight teams in the entire league! No conferences, just two divisions. The Celtics were there from day one, while the 76ers began as the Syracuse Nationals before relocating to Philadelphia in 1963. Talk about OG status in the basketball world!

What really gets me about this rivalry is how it's stood the test of time. Through decades of rule changes, expansion teams, and evolving playing styles, these two franchises have maintained their competitive fire. The intensity between them is absolutely bananas - it's like watching two heavyweight boxers who know each other's every move but still bring the heat every single time they step into the ring.

The London setting added such a cool twist to this classic matchup. Seeing British fans going wild for basketball moves that were invented when their grandparents were kids was seriously awesome. It's crazy to think that what started as a small American league with just eight teams has become this global phenomenon where historic rivalries can play out in front of international audiences.

Here's what makes this rivalry so special:

• Longevity: These teams have been competing since 1946

• Frequency: In the early days, they played each other constantly due to the small league size

• Evolution: Both franchises have adapted while maintaining their core identities

• Global appeal: The London game demonstrates how historic NBA rivalries resonate worldwide

As I watched the game unfold, I kept thinking about all the legends who've battled in this rivalry - from Bill Russell and Wilt Chamberlain to Larry Bird and Julius Erving, right up to today's stars. The thread connecting all these eras is the sheer competitiveness and respect between these two iconic franchises. It's not just a game; it's living history playing out right before our eyes.

Honestly, being there felt like witnessing basketball royalty going head-to-head. The energy in the arena was electric, with fans from both sides bringing that proper intensity. When you realize you're watching something that's been happening for nearly 80 years, it gives you chills. This isn't just another regular season game - it's a continuation of one of sports' greatest stories.

What I love most is how both teams have managed to stay relevant through all these years. They've had their ups and downs, but they always find their way back to competitiveness. That's the mark of truly great organizations. The fact that in 2025, these two original franchises are still among the NBA's elite? That's absolutely legendary.

The London game reminded everyone that some things in basketball are timeless. While the game has evolved dramatically since 1946, the fundamental appeal of seeing two historic rivals battle it out remains as strong as ever. It's like fine wine - it just gets better with age. And let me tell you, witnessing this piece of basketball history in person was an experience I'll never forget. Pure basketball magic, through and through!
