They've played the equivalent of a Kansas State schedule. Color me not impressed. Any ranked team that has 2 losses would be undefeated on that cake schedule of Tech's.
Compare Tech with Notre Dame and Ohio State.
Notre Dame: Pitt, Michigan, Michigan State, Washington, Purdue, USC
Ohio State: Miami of Ohio, Texas, San Diego State, Iowa, Penn State, Michigan State
There is no way in hell that Texas Tech is undefeated on either of those schedules.
