The main reason for better coaches and better players was P5 money and P5 status. P5 money buys better coaches. P5 status brings in better recruits. It won't happen overnight, but now that BYU is on the same level, making the same money, these advantages are over. If you don't understand or recognize this, you don't understand college football, at all. And once Whit retires, this advantage will also be gone.
Enjoy it while you can, because it's almost over.
