Boise State sold out their Fiesta Bowl ticket allotments both times they made it there, and they sold all their tickets for their last two season openers, in Landover, Maryland and Atlanta, Georgia. They have also drawn higher ratings for their BCS games than Virginia Tech has. The "Boise won't travel" stuff just isn't true.
Would Boise outsell Virginia Tech in New Orleans? I can buy that they would outsell Virginia Tech in Glendale, Arizona. I'm not a Hokie apologist, but Virginia Tech has had bad matchups in some of their Orange Bowl games against Stanford, Kansas, and Cincinnati. Boise has been to two BCS games, but had a compelling matchup against Oklahoma in one of them.
