I e-mailed Michael Russo from the Star Tribune and here is what he said:
I get this question all the time. Trust me, it's a topic of much debate, even inside the sports department, but our newspaper's current policy is that it remain an 'it' rather than a 'they'. Several papers across the country have this policy, including my old newspaper. It never bothered me there because I covered a team that was plural, so it only affected me when I referred to the Lightning, Wild, etc. Here, it took a while to get used to. Personally, I think the Wild is a collective noun, and thus, like you, we should consider it plural. It often makes for awkward-sounding sentences. Just my opinion though. The paper considers the word "wild" singular.
Plese feel free to fix the Wild page accordingly. Thank you
