Georgetown and SDSU thought they should advance with ease. Look at George Mason, they went to Final Four as a 11 seed, and they upset good teams along the way like UConn. They beat MSU, UNC and UConn on the way to the Final Four.
Saying FGCU have no chance is stupid based on the tournament result. They dominated both teams. It's not like they made a miracle buzz beater shot to beat them. They flatout just dominated both teams. It wouldn't surprise me if FGCU beat Florida. FGCU just shredded the 2nd best defensive team in the country in Georgetown, the same Georgetown who locked down Big East teams.
Florida tends to struggle against teams with good guard plays. In the tournament, FGCU guards have been fantastic and were unfazed by the full court press. With great guard play and their ability to be fearless, I can see the upset. Florida likes to force turnovers via full court press and half court trap.
