Why brands sponsor sports teams (and why It's not always a WIN)?

Quick disclosure: I'm a big fan of Dziki Warszawa, so I might be a little biased here. But watching a local team grow with a shirt sponsor on their jersey got me thinking about why so many brands pour money into sports sponsorships in the first place — and why it doesn't always pay off.
Let's start with the upside.
First, sponsorship buys you instant emotional connection. Sports fans are loyal, loud, and emotionally invested in a way most other audiences just aren't. When your logo shows up on a jersey a fan wears every week, you're not interrupting their day like a normal ad would — you're part of something they already care about. That kind of goodwill is hard to manufacture any other way.
Second, it's genuinely great for visibility and reach, especially at a fraction of the cost of traditional media. A season-long shirt deal gets your name in front of fans at every match, every photo, every local news clip — for months, not just a 30-second spot.
But it's not all wins.
The biggest risk is reputation. You're tying your brand to real people, and people are unpredictable. A scandal, a bad season, a controversial player — suddenly your logo is stuck next to a story you never wanted to be part of. You can't fully control that once your name is on the shirt.
The second risk is simply picking the wrong team or league for your brand. Sponsoring a team your actual customers don't care about is just money down the drain — no emotional connection, no reach, just a logo nobody notices. Fit matters just as much here as it does in any other kind of marketing.
So sponsorship can absolutely be a smart move — heart and visibility on one side, reputation and fit risk on the other. Like most things in marketing, it comes down to knowing exactly who you're trying to reach, and whether this is really where they are.
