Thurs. night game
BC at Va Tech -13.5
Heres my question maybe somebody can answer this. The BCS standings with computer do they use margin of victory again? I heard it matters again by how much you win again some were?
So with VA-Tech playing Miami next week do they look past this game & win but not by a huge margin or do they blow BC like they did to ever other home game this year?
