The best underdogs to pick for your March Madness bracket

Everyone loves an underdog. That's why figuring out which ones to support in the NCAA Tournament is one of the most fun aspects of March Madness. When that inevitable first upset occurs, it's a good feeling to be one of the lucky ones who backed that scrappy squad on your bracket.

Among the first round games in this year's Big Dance with at least five seeding lines between teams (No. 6 vs. No. 11, No. 5 vs. No. 12, etc.), FiveThirtyEight gives seven lower-seeded teams at least a 20 percent chance of advancing to the round of 32. That group includes three No. 11 seeds, three of the "lucky" No. 12 seeds and even one No. 13 seed.
