Oklahoma State is a 10 seed and plays Florida Gulf Coast ( a 7), then possibly Florida (a 2 seed) in Tallahasse.
Iowa State is a 10 seed and plays Dayton (a 7), then possibly Kentucky (a 2) in Lexington.
Some outfit named Texas is a 5 seed and plays Western Kentucky (a 12), then possibly Cal (4 seed) in Berkeley.
I predict at least 4 first round wins - and would not be surprised if all 5 move on.
