It'll be interesting.
K St is already ahead in the computers, but only by 3.5 spots.
They still have solid teams on their schedule in Texas Tech (6-1), OK St (4-2), AT TCU (5-2) and Baylor (3-3) then Texas (5-2) to end the season. That's 23-10 cumulative.
Of the 5, only Baylor is not better than .500
Oregon still has Colorado (1-6), AT USC (6-1) and Cal (3-5), Stanford (5-2) and then of course AT Oregon St.(6-0). That's only 21-14 cumulative.
Colorado is by far the weakest of all 10 teams, and California is also under .500 having only won 3 games so far. But Oregon St is undefeated, (although I believe they will lose when they go to Stanford in a couple of weeks).
Looking at all of that it would seem that K ST has the better remaining schedule by a decent margin, if not overwhelmingly so, and IMO could definitely create more separation between themselves and Oregon in the computers.
Their biggest obstacle IMO is the human voters who seldom do more than move up the winners and move down the losers, without ever re-evaluating their earlier positioning.
