About Gray Duck Data
Gray Duck Data tells the stories behind Minnesota sports — with real data, honest statistics, and visualizations built by hand. One sharp question per story. Methods always public.
The auroras on this site change color with the team. The north star — the data — stays fixed.
Who makes this
I'm Haley Eidem — a quantitative UX researcher and data scientist (computational genetics PhD) and a lifelong Minnesota sports fan. I've spent 8+ years at Google and DigitalOcean turning messy data into decisions; this site is where I do that for the teams I love, in public.
Every story links its data and code. If something looks off, tell me — being wrong in public and fixing it fast is the whole point of showing your work.
Gray Duck Data is independent and unofficial — not affiliated with any team or league. And yes, it's called Duck, Duck, Gray Duck.
