March Madness is back, and it's time to fill out your bracket.
Through the first two rounds of the tournament, it's important to include a few upsets in your bracket. They don't have to be stunners, but a few double-digit seeded teams taking a win in the first round is to be expected. The key is choosing the right ones.
By taking a look at the lines in Las Vegas, we can get a better idea of which upsets could occur in the first round. Sometimes, a lower-seeded team is actually favored over their higher-seeded opponents. Other times, the spread just isn't as big as you might think, hinting that Vegas sees a potential upset in the works.
Below we examined the 15 first-round upsets most likely to happen based on the spreads. All lines courtesy of the Westgate Las Vegas Superbook.
