So far, I've only checked the last 25 years, back to the 1998-1999 school year. This year, 2022-2023, is the ONLY year that both the football and the men's basketball teams have each achieved the winning percentage that they have this year, that is, approximately 77% for both teams.
I look forward to discovering (by my own research if necessary though I welcome input from others) how many, and which, other years we have had both teams at 77% W-L. I would guess that maybe the total number of such years would be less than 12, going all the way back another 100 years or so to whenever Furman had both football and basketball teams.
OK, this edit at 12:37 PM on 3/30/2023:
My guess was correct, however instead of anywhere near 12 years, it is only 2 years.
I find, going all the way back, only ONE OTHER YEAR, 1927-1928, in which BOTH TEAMS have finished with a 77% or higher W-L record.
In 1927-28 (95 years ago), football was 10-1, and basketball was 16-3.
The only years for men's basketball at 77% or above have been (total of 9 years - 3 of those in the last 25 years [actually all 3 of those 3 of the last 25 years coming in the last 3 years including 2022-23):
1929-30, 16-1
1930--31, 15-2
1931-32, 15-1
1952-53, 21-6
*1974-75, 22-7 (actually "only" 76%)
1979-80, 23-7
(Note that 6 of our 7 total appearance seasons, and our 1 previous win until the one on 3/16/2023, in the NCAA Tournament, were in the same decade as the 2 seasons immediately above.)
*2018-19, 25-8 (actually "only" 76%)
2019-20, 25-7
2022-23, 28-8
The only years for football at 77% or above have been (total of 21 years, 4 of those in the last 25 years):
1890, 2-0
1892, 1-0
1920, 9-1
1921, 7-2-1
1923, 9-2
1926, 8-1-1
1927, 10-1
1932, 8-1
1933, 6-1-2
1935, 8-1
1936, 7-2
1953, 7-2
1980, 9-1-1
1983, 10-2-2
1985, 12-2
1988, 13-2
1989, 12-2
2001, 12-3
2004, 10-3
2005, 11-3
2022, 10-3
AS STATED ABOVE:
I find, going all the way back, THERE HAS BEEN, BESIDES THIS YEAR, 2022-2023, only ONE OTHER YEAR, 1927-1928, in which BOTH TEAMS, football and men's basketball, have finished with a 77% or higher W-L record, in the entire history of Furman University.
Corrections welcome.
