This is to say who realistically can get into the 12-team playoff undefeated and/or as an at-large. Does your school get into the playoff if it is undefeated?
Currently, the pathway is available to the 65 P5 schools and an AAC school if it goes undefeated two straight years and beats marquee opponents.
With the 12-team playoff, the door opens for more schools but I don't believe everybody.
Obviously the 68 P5 schools going forward plus Notre Dame will have access, but who else?
In my opinion, if the following schools/conferences go undefeated in most years, they will be in.
AAC
MW
Army
UConn
Sun Belt
The following schools/conferences will still have an uphill battle due to weak schedules:
MAC
UMass
C-USA
