Oregon 12 vs Okie State in San Jose
Ole Miss 12 vs Wisconsin in Salt Lake City
Akron 12 vs VCU in Auburn Hills
Cal 12 vs UNLV in San Jose
Wisconsin is the least likely 5 seed to lose in my opinion.
So far I have not been impressed by VCU but I don't know enough about Akron. Michigan will beat either team so it might be worth it to pick the upset in the bracket.
Cal & Oregon could win but I like UNLV's big man Bennett and the fast paced style.
