My issue with this line of thinking is it ignores the bias of the committee. 2-loss teams or a 1-loss team that lost to NIU should not be above BYU. There's also no reason SMU should be ranked above BYU either when we won the head-to-head.
I understand that if we "just win" that it'll "sort itself out" but just saying that and not being upset about the current ranking ignores how royally screwed we could be by not having been ranked above an SMU or Boise St when we should be.
Being ranked 14 currently sets us up for getting hosed in the following (very possible) scenarios.
Scenario #1: BYU beats ASU&Houston but loses to CU in the CCG. By not being ranked higher, we very likely will be the first team out. Narrowly missing the CFP despite only 1 regular-season loss while 2-3 loss SEC & B1G teams with worse resumés get at-large bids.
Scenario #2: BYU wins the CCG but is jumped by Boise St for a 1st round bye. Rather than being the #3 or 4 team w/ a 1st rd bye, we're the #12 seed playing on the road against Ohio St before we could ever sniff an NY6 bowl.
Scenario #3: Albeit unlikely, Army somehow wins out and beats Notre Dame next week. This could mean the B12 champ gets left out of the CFP completely due to Boise St & Army surpassing us in the rankings.
All of these scenarios are now much more likely because BYU is ranked lower than it should be based on resumé and head-to-head results alone. I know at this point we will be lucky just to play in the CCG, but the argument of "just win and it'll sort itself" and "rankings don't matter" is ignoring the unequal playing field of bias and brand-perceptions that would absolutely hurt us now and in the future unless we go undefeated or win the conference--a luxury those other brands don't have to worry about.
