Going to compare the CC top-6 model, vs the top-4 bcs model to see which produced the most final-4 ranked teams using the AP poll
2000 no difference in teams selected
2001 no difference in teams selected
2002 Final top 4: Miami, Ohio St, Georgia, USC
CC: Miami, Ohio St, Georgia, Washington St
2002 the top-4 model had 4 teams in the final top-4, while the CC model had 3/4 (USC was technicaly co-champs but lost the head to head to WSU. Iowa was also co-champ of the Big-10 as they and Ohio St did not play each other and Iowa was ranked 5 compared to WSU at 6, not sure how that would have worked out, though both Iowa and WSU finished outside the top-4
2003 No difference in teams selected
2004 top-4: USC, Oklahoma, Auburn, Texas
CC: USC, Oklahoma, Auburn, Utah
CC had 4 teams in the final AP top-4, while the top-4 method had 3 (though the results are reversed if the coaches poll is used)
2005 no difference
2006 top-4 Ohio St, Florida, Michigan, LSU
CC: Ohio St, Florida, USC, Louisville
Both resulted in 3 of 4 teams in the final 4. Florida, Ohio St, USC and LSU were the final 4 that year.
2008 top-4 Oklahoma, Florida, Texas, Alabama
CC: Oklahoma, Florida, USC, Utah
top-4 model produced just 2 teams in the final 4, while the CC model produced 3 teams in the final 4.
2010 Top-4 Auburn, Oregon, TCU, Stanford
CC Auburn, Oregon, TCU, Wisconsin
Top-4 model had all 4 of the final 4 teams, while the CC had 3
2011 Top-4 model LSU, Alabama, Okie St, Stanford
CC: LSU, Alabama, Okie St, Oregon
Top-4 model had 3 in the final 4, while the CC model had all 4.
The Conference champion model produced 1 more team in the final top-4 than using the final top-4 in the rankings. Very close, but the CC model is improved now, due to the fact that both the PAC-12 and Big10 have CCG’s, and though the Big-12 does not, they do play a true round robin.
