Let's say you're a rabid college basketball fan, but even a die-hard like you isn't up to speed on the most granular performance details of teams out of the Big West or the Ohio Valley Conference. Plus, by the way, you still want to win your bracket.

Giant Killers is here to help.

One proven method for putting distance between you and your competitors in the bracket pool is correctly picking a small but ultimately crucial number of upsets. Here are the 10 most likely such games in the first round, according to GK methodology.

As always at Giant Killers, we're looking exclusively at games in which an underdog defeats an opponent seeded at least five lines higher. Choose wisely (meaning, no, don't go with all 10 of these), and watch your bracket ranking soar to new heights. Good luck!
