This has been updated after the final polls for the 2007 season.
OK, here's how this was calculated. I took each team's ranking in every year-end poll since the AP started in 1936. Once 2 polls were involved, I always used the higher ranking. Sliding scale points were awarded for every year that a team ended up ranked, and 10 points were deducted for each losing season. The scale was determined before seeing where teams ended up.
For each year since 1936, a team earns points based on these criteria:
NC (#1) in either poll = 100 points
02 -> 05 = 65, 55, 50, 45 points, respectively
06 -> 10 = 40, 37, 34, 32, 30 points
11 -> 20 = 28, 26, 24, 22, 20, 18, 16, 14, 12, 10 points
21 -> 25 = 08, 06, 04, 03, 02 points
non-ranked, but .500 or above = 0 points
losing record for the year = minus 10 points
Here are the all-time totals, updated after the 2007 final polls:
01. 2308 - Oklahoma

New this year, I have given National Championship credit for those earned prior to 1936, on a sliding scale based on 12-year periods.
1869-1899 - 10 points for each MNC (no top teams here, almost all Ivy League)
1900-1911 - 25 points for each MNC
1912-1923 - 50 points for each MNC
1924-1935 - 75 points for each MNC
Here are the all-time totals, updated with the pre-1936 MNC points:
01. 2480 - Notre Dame (MNCs in '24, '29, '30)
02. 2308 - Oklahoma
03. 2285 - Alabama (MNCs in '25, '26, '34, 2/3 for '30)
04. 2180 - Michigan (MNCs in '01, '02, '23, '33)

Note - Illinois, with MNCs in '14, '23, and '27 fails to make the top 30.
