Top upset picks: West | South | East | Midwest

Because you can never have too much expert analysis, we asked Jay Bilas to make a guest appearance and offer his insights on the most-likely upset predictions seen by the Giant Killers team. When it comes to lower seeds toppling the top squads, consider five of these six games GK-tested and Bilas-approved.

UMass Minutemen vs. Iowa Hawkeyes/Tennessee Volunteers

GK upset odds: 78.4 percent / 70.1 percent

As the model identifies, UMass was overseeded as a No. 6, and Tennessee and Iowa are both far more capable than the No. 11 seed would suggest. Iowa is deep and talented, and particularly with Gabe Olaseni, the best hedge defender I saw this season, the Hawkeyes can contain Chaz Williams off ball screens.
