You're talking out of both sides of your mouth.
Also, while BYU is certainly craving a BCS win, it is asinine to say it is the only indicator of a successful season.
I'll just flip that faulty logic on you. The only mark of a successful program is winning a national championship. BYU has done that, Utah has not. BYU will always have the ultimate trump card if you want to resort to debating in the manner you did.
