Jersey Chronicles: No. 27 — The Forgotten Number That Traveled from Seattle to OKC
When you think of iconic jersey numbers in NBA history, a few stand out immediately—No. 23, 24, 33, maybe even 6. But then, there are the underdog digits—the ones that don’t get the spotlight but still tell stories of transition, grit, and evolution. One of those numbers? No. 27 for the Oklahoma City Thunder (and formerly, the Seattle SuperSonics).
Let’s go ahead and crack open the vault.
Here’s the deal: since the franchise’s birth way back in the 1967-68 season, a total of 51 unique jersey numbers have been worn by various players. That’s right—whether it was during the vintage Sonics era or the sleek Thunder rebrand, each digit has seen a different set of personalities, talents, and chapters.
And now? We’re diving deep into one of the more low-key numbers that still packs a punch—jersey No. 27.
Before OKC Had Thunder… There Was Sonic Boom
First, let’s not forget the roots. The Seattle SuperSonics were the original iteration of today’s Thunder franchise. Even though Seattle has been itching for its own team again—and may well get one in the future (imagine the nostalgia if that happens!)—the Thunder technically carry the Sonics’ history with them. This means any player who once wore green and gold is still a part of Oklahoma City’s story.
So when we talk about who wore No. 27, we’re not just talking OKC post-2008. We’re going way back.
Four Warriors, One Digit
So far, only four players in the entire franchise history have ever worn jersey number 27. That’s rare air, folks. This number hasn't been pulled off the rack too often, and that makes every story behind it worth remembering.
While we’re focusing on the 28th entry in Thunder Wire’s ongoing jersey number series, it’s these lesser-known players—guys who put in the work, who might not have their names in lights—that make this journey so much fun to follow.
Let’s talk about the most notable name among them.
Enter Johan Petro: A French Big Man with American Ambition
One of the more memorable players to sport the No. 27 jersey was Johan Petro, a 7-foot center from Paris, France, whose NBA journey kicked off with some serious international flavor.
Drafted 25th overall in the 2005 NBA Draft, Petro joined the league thanks to the Seattle SuperSonics, who saw potential in his frame and skill set. His arrival brought a breath of European flair to the Pacific Northwest, at a time when international players were beginning to truly make their mark in the NBA.
Petro's time with the Sonics was... let’s say a mixed bag. But it wasn’t for lack of effort.
The Petro Era: Grinding Through a Franchise Shift
Johan Petro didn’t just get caught up in a positional battle—he got swept up in a whole franchise relocation. As Seattle prepared for its controversial move to Oklahoma City in 2008, Petro remained a constant during that turbulent transition.
He wore the No. 27 through both the final years of the Sonics and the early stages of the Thunder’s birth. That continuity gives him a unique place in team history—not many players can say they experienced both eras while sticking with the same jersey number.
Petro played parts of four seasons with the Sonics/Thunder, contributing 5.7 points and 4.5 rebounds per game. Modest stats, sure. But when you're developing as a young center on teams filled with uncertainty, that's no small feat.
Oh, and did we mention? The dude was a legitimate shot-blocking presence on his best days. Fans might remember the occasional flashy swat or two that brought the crowd to life.
Post-Sonics: Mile-High Moves
Petro’s journey with the Thunder didn’t last forever. In 2009, he was traded to the Denver Nuggets, closing the chapter on his role in Oklahoma City’s foundation. While he never became a superstar, Petro remained in the league for several years and earned respect as a dependable big man off the bench.
He’d later play for the New Jersey Nets (before they went full Brooklyn), and even made a return overseas to continue his basketball career.
It wasn’t always glamorous—but Petro’s path shows how much resilience it takes to stick around in the NBA.
Digging into the Stats
For all you statheads out there, let’s run it back:
-

Career Avg with No. 27: 5.7 PPG, 4.5 RPG
-
Drafted: 25th overall in 2005
-

Not mind-blowing numbers, but again—it’s the context that makes it fascinating.
Why Jersey No. 27 Matters More Than You Think
There’s something pretty cool about a jersey number that doesn’t scream “legendary,” but still has character. No. 27 has been a symbol of transition—a digit that survived a move across state lines, two team names, and one player who stayed loyal through the change.
We often reserve our praise for players with All-Star nods and Hall of Fame speeches. But Petro and the few who wore No. 27 deserve a nod too. They’re part of a franchise’s bones—the layers beneath the KD and Westbrook headlines.
What’s Next for 27?
As Thunder Wire continues its deep dive into all 51 jersey numbers, it’ll be interesting to see if No. 27 ever returns to rotation with a new rising star. Could a rookie claim it and rewrite its legacy? Could a gritty role player bring it back to life on a playoff team?
Only time will tell. But one thing’s for sure—there’s history stitched into that jersey, even if it doesn’t hang from the rafters.
