Welcome back to Giant Killers!

It's hard to believe this project is now in its fifth year, but as long as unheralded teams keep pulling off shocking upsets in the NCAA tournament, we'll keep trying to project those events before they happen. This year, we've made significant upgrades to our model, as we continue to learn from historical data. So consider today's post a guided tour so you know your way around the next couple of weeks.

First, if you still don't know what a Giant Killer is, glance over to the top right of the main blog page for a quick refresher. We strongly recommend reading about our methodology for a deeper understanding of how our project works and what metrics we utilize. And if you still have questions, just take a trip over to the GK Mailbag and send us a note.
