The problem with 16 teams with auto bids for all conference champs is much of the G5 wasn't even FBS when the split happened (only 52.5% were FBS). Many came in the 2000s (29.5%). A bunch since 2012 (21.5%). Why should schools that have been FBS 10 years or less have equal access? I think D1 needs to go to 3 sub divisions. The P5 all go to 16 teams (80 total) and stay FBS. The remaining FBS teams add the top FCS schools and become FCS A, and the remaining FCS schools become FCS AA.
FBS - 80 teams
FCS A - 90 teams (53 current FBS teams plus Top 37 FCS teams)
FCS AA - 95 teams
ACC all 14 schools were FBS in 1978
B1G all 14 were FBS in 1978
B12 11 of 12 were FBS in 1978, all 12 before 2000
P12 all 12 were FBS in 1978
SEC all 16 were FBS in 1978
MAC 10 of 12 were FBS in 1978, all 12 were FBS before 2000
MWC 10 of 12 were FBS in 1978, all 12 were FBS before 2000
AAC 8 of 14 were FBS in 1978, 10 of 14 were FBS before 2000, 12 of 14 were FBS before 2012
CUSA 2 of 9 were FBS in 1978, 4 of 9 were FBS before 2000, 6 of 9 were FBS before 2012
Sunbelt 2 of 14 were FBS in 1978, 5 of 14 were FBS before 2000, 6 of 14 were FBS before 2012
57% of the Sun Belt and 33% of CUSA joined the FBS after 2011.
64% of the Sun Belt and 55% of CUSA joined the FBS in the 2000s.
