I would prefer a staright-12 system, but regarding points that have been made in the past around here:

1) I believe I have said a problem with P5 autobids and just one general autobid for the whole G5 is that it could create a legal issue, because it would formally treat P5 and G5 conferences differently, and maybe that idea influenced this proposal. This top six champs thing seems more defensible to this non-lawyer from a legal POV, lol.

2) Am glad there are no autobids for any particular conference champs, as that precludes a big CCG upset putting a 7-5 team in. This is also inconsistent with the notion of maximizing the value of P5 CCGs, because P5 CCG s will not be guaranteed play-in games for both participants as they would be under 5-1-2 or 5-1-6.

3) Mystified as to why top 4 conference champs would get byes, not the 4 highest ranked teams. Makes no sense, imo.

That said, this is just a proposal by the working committee, we do not know if it will be approved. It could be modified significantly by the full CFP membership or rejected entirely.
