The CFP Committee will definitely not take Baylor, for PR reasons as mentioned above, undefeated or not. Washington could make it in as a 1-loss Pac12 Champ, but they'd save the Committee a bit by going undefeated.
2 teams from the same conference (Clemson and Louisville, Ohio State and scUM, Bama and A&M, etc.) could make it in if there's some upsets in conference championship games or if Washington State upsets Washington in the Apple Cup.
I happen to think that at season's end, there will be a lot of teams vying for that #4 spot, even non-divisional winners if they pass the "eye test." Let's say scUM runs the table until they lose to the Buckeyes in a close game (7 points or less). They would definitely have a case to get in if Washington loses a game they shouldn't lose or if a team that wins one of those conference championship games has 2 or more losses.
This is the year that the CFP definitely would benefit from an 8-team playoff. Right now as the rankings stand it would be:
(1) Alabama vs. (8) Wisconsin
(4) scUM vs. (5) Washington
(2) Ohio State vs. (7) Louisville
(3) Clemson vs. (6) Texas A&M
Those would be some great matchups. I know things will change, and teams will lose games head-to-head, but sooner or later the playoff needs to expand to 8.
