BYU has accomplished the two most important goals.
1) Increased revenue - BYU has dramatically increased revenues over MWC revenue's. Estimates put BYU in the 8-10 mill range/season already.
2) Exposure - BYU was televised 10 times last year alone. Bravo!
Bonus Points - BYU has also made themselves far more flexible to make a move if the "right" situation comes available.
All this talk of relevancy is a made up argument by fans who are bitter over independence vs. BCS affiliation. The talk over November schedule is a weak argument as well. The only difference is that Utah is no longer available. I have no doubt that BYU will improve late season schedule, and it will certainly be better than BYU's traditional late season slate of obstacles of the past.
The fact is that BYU has put together three (perhaps four) seasons over the last 70-80 years that would have given them any consideration for a national championship or serious BCS consideration. What this comes down to is that under BYU's current situation they have far better funding and far better exposure. These improvements help BYU to improve facilities, improve recruiting and improve performance against stiffer competition.
As a fan I am delighted over our current situation. In addition to the ND and Boise State games I would love to see BYU develop annual rivalries with the following programs to increase national interest:
Anyway, I am very happy and I applaud BYU for the bold decisions they have made.
