Modeling the world's most famous decisions.
Welcome! The Round Robin is my data passion project. Leveraging 16 years of men's college basketball Bracketology, I'm building a portfolio of interactive forecasts and models for some of the world's most famous, and divisive, decisions. If you'd like to see them, join the email list below.

What is The Round Robin?
Predicting decisions made behind closed doors.
I built The Round Robin around three things I care about more than any single prediction: understanding how a decision actually gets made, seeing a model's real record instead of just its best calls, and building your own version instead of only reading mine. Those three pillars are the whole site.
01 · Learn the process
Who actually has the vote, and what they weigh. The guides cover the real criteria and the calendar behind each call, before any model gets involved.
02 · Meet the model
Each model runs on the same evidence the real decision-makers use. I publish the full record next to every prediction, misses included, so you're never just taking my word for how good it actually is.
03 · Build the case
The studios hand you the same data the model uses. Build your own version, save it, share it, and see how it holds up against the real result, and against mine.
The guides
Each guide explains how one of these decisions actually gets made, in plain language, so you understand the process before you start predicting it.

Who's behind it
I've spent sixteen years arguing about how these calls get made.
I'm Grant Hansell. I started filling out bracket projections because working out how the selection committee thinks was its own kind of fun, and I kept at it long enough that Bracket Matrix ranked my projections in the global top ten. The Round Robin is what happened when I decided to build the tool I'd always wanted, and use it to model the Hall of Fame and the Oscars too.
I'm one person. I use AI to do work that used to take a whole team, which is how I keep three models running and keep shipping new tools on my own. Now I'm opening it up to everyone else.
Where the name comes from
The Round Robin is the fairest evaluation format ever designed. Everybody gets measured against everybody and the results speak for themselves. That is how these decisions ought to be made.
Questions
Why is this closed right now?
I'm still finishing pieces of it. Oscars Studio is the big one left, and I'd rather get it right for a smaller group than open the doors on something half-built.
How long does the alpha last?
No promises on when it opens up further. I let people in as I'm ready, whenever that ends up being.
I don't have a code. What happens if I join the waitlist?
I save your email and reach out when I open more spots. No spam and no other lists, just the one email when it's your turn. Want off the list before then? Email me and it's gone. Details are in the privacy policy.
What can I do without an access code?
Everything under "Available now": the full 2026 bracket, HoF classes by year, the Oscars 2026 forecast, and every guide. No sign-in required.
Come make the calls yourself.
