BYU's goal is to make a bowl game, which is why Kalani only needed 6 wins to secure a contract extension.
BYU doesn't expect to win 10 games. It doesn't expect to beat Utah. And it is not going to devote the type of resources necessary to compete at the highest level.
BYU's goal is to be on national TV as frequently as possible. Winning those games doesn't matter as much as playing them.
BYU's secondary goal is to make money, which coincides nicely with its first goal (being on national TV).
As for winning, BYU wants to make a bowl game every year. But there is no expectation or commitment to do anything more. If BYU happens to surprise a few teams and win 8-10 games, that's great. But that's not the standard by which Tom or anyone else in the Administration is measuring the program. Why? Because the effort and expense necessary to go from 6 wins to 9 wins is significant, but the return isn't materially different. Whether BYU wins 6 games or 9 games, it will still go to the same bowl game, will still have relatively stable and strong attendance, and will still be on national TV 5-6 times per year.
