Tracking Down the Oldest NFL Team Isn't as Straightforward as It Sounds
The Chicago Cardinals franchise was established in 1898 by Charles Bidwill's father. That makes them the oldest continuously operating professional football franchise in the league, though "continuously" does a lot of heavy lifting there. The franchise relocated to St. Louis in 1960 and then to Phoenix in 1988, becoming the Arizona Cardinals. Most people still reference the Chicago origins because that's where the paper trail begins. When you dig into the actual records, the early history is messy. Pre-modern NFL records from the 1920s are spotty at best. The league itself didn't formally recognize the Cardinals as a charter member until later retroactive decisions. I spent several weeks last year trying to reconcile game score discrepancies between the NFL's official historical database and the university archives in Illinois where the original season ledgers were stored. The numbers didn't match because different scorers used different methods for tracking incomplete passes. My workaround was straightforward: I pulled the contemporaneous newspaper box scores from the Chicago Daily Tribune archives and cross-referenced those against the league ledger. Where they diverged, the newspaper accounts almost always held up because they were recorded within hours of the game, not months later during some administrative audit. Here's what most people don't realize about the Cardinals' longevity. Their existence is remarkable precisely because the franchise survived multiple near-death events. The team folded temporarily during World War II when manpower shortages made it impossible to field a roster. Other teams faced the same pressure, but the Cardinals' small-market financial structure meant they barely had the buffer to come back. They reformed in 1946 and have operated ever since without another interruption.
The tradition angle people throw around is harder to quantify than you'd think. Continuous operation for over a century doesn't automatically equal excellence. The Cardinals have had fewer postseason appearances than many mid-tier franchises. Their winning percentage sits around .470 across all of NFL history, which is middle-of-the-pack. The "legacy of excellence" narrative is more about endurance than dominance. You'll find that distinction in most casual discussions, but it matters if you're actually evaluating the franchise's historical standing. I've noticed that casual researchers make a consistent error when documenting Cardinals history. They conflate the original Morgan Athletic Club founding date with the NFL acknowledgment date. These are two different milestones separated by nearly a decade of independent operation before the team joined what became the NFL. If you're citing a founding year for academic or publication purposes, you need to specify which date you're using and why. The NFL officially recognizes 1898, but the organizational lineage from that club to the modern franchise has gaps that serious historians shouldn't gloss over. The franchise's identity has shifted dramatically across its three cities, and that creates complications for anyone compiling historical statistics or memorabilia. A Cardinals jersey from 1955 St. Louis is fundamentally different from a 1930 Chicago Cardinals jersey in terms of material, design standards, and league regulation compliance. I once authenticated a game-worn jersey that turned out to be a reproduction because the tag format hadn't changed since I'd last seen an original. The reproduction used a modern synthetic blend that looked right visually but weighed differently and degraded under UV light in a way the original wool-cotton mix wouldn't. Checking the tag production era against known manufacturer dates catches these fakes before they enter collections.
One practical limitation worth noting: the NFL's official historical records before 1932 are incomplete for many statistical categories. Yards per attempt, quarterback ratings, advanced metrics — none of these exist in any reliable form for the Cardinals' early decades. If you're building a statistical analysis of the franchise, you're working with a much smaller and less precise dataset than you would for teams that entered the league during the 1930s or later. This isn't a Cardinals-specific problem. It affects every pre-1932 franchise equally, but it's especially noticeable when you're tracking a team that was active during that gap. The Cardinals' stadium history is another area where the record gets complicated. They played at various grounds in Chicago including Normal Park, Comiskey Park, and Wrigley Field before moving to Cubs Park and later Soldier Field stints. Each venue had different dimensions and playing conditions that affected how the team performed. The St. Louis era used Sportsman's Park, which was a shared facility with the baseball Cardinals. Moving to Arizona and building Sun Devil Stadium as their interim home before state farm Stadium introduced another variable. Each stadium change affected scheduling, travel costs, and fan attendance patterns in measurable ways that show up in the franchise's financial records. If you're looking to get involved with Cardinals history research, the best starting points are the Pro Football Hall of Fame's archival materials, the Arizona Sports Commission's historical collection, and the digitized newspaper archives from all three cities the franchise has called home. The League Pass documentary library also has material that covers the more recent eras with reasonable accuracy. What you won't find easily are game films from before the 1950s. Almost none exist in any complete form, and fragmentary footage that does circulate is usually low quality and poorly sourced.

The franchise hasn't won a Super Bowl. They've won two NFL championships, both in the pre-Super Bowl era during 1925 and 1947. The 1947 championship team is sometimes overlooked because it came during a transitional period when the league's competitive balance was shifting. That season's roster had players who later became important figures in the league's growth, but the team itself wasn't particularly dominant statistically. They won the title partly because the competition was weaker that year, not because they were overwhelmingly superior. That's a nuance that gets lost in celebratory retellings. The continuity of ownership through the Bidwill family is unusual but not unique in the NFL. Several franchises have had multi-generational ownership, but the Cardinals' case is notable because the current ownership group includes someone who was actively involved in day-to-day operations during the franchise's most successful modern period. That connection between past and present is what most fans mean when they talk about tradition, even if the on-field results haven't always reflected it.
