According to Bart Torvik, Xavier's non-conference schedule this year includes games against three top-50 teams: Ohio State, one of Va Tech and Memphis, and Oklahoma State. One home, one neutral, one road. Throw in some buy games and the Shootout and Xavier has a very solid slate heading into the Big East season. The foundation of the tournament resume will be built on OSU, VaTech/Memphis, and at (another) OSU. If we're talking about anything else in March something very bad or very surprising has happened.
Oklahoma State will be Xavier's only true road game in the non-con.
