The first weekend of the NCAA tournament often sees an underdog or two rise up and win their first two games and advance to the Sweet 16.
That's when reality usually takes hold. A double-digit seed goes up against a top seed or a No. 2, and they get hit hard and lose their footing.
But every once in a while, a double-digit seed survives. That's the case this year for the Dayton Flyers. The 11th-seeded Flyers may have had a fortunate draw because they faced 10th-seeded Stanford in the Sweet 16, but they took advantage and beat the Cardinal by 10 points.
On the other end of the spectrum, top-seeded Florida survived a tough game with UCLA and continues its march toward a possible championship.
