Really? that is why I pretty much excluded them from the OP

Look at the 4 B1G schools in my 2nd post on the first page. Look at how often games were played at B1G schools with no return trips. Easier to rack up B1G wins if you get to play games where you get to sleep in your own bed on gameday.

Iowa and the SEC
Arkansas - 1925 @ Iowa City :::: no return trip @ Arkansas
Texas A&M - 1931 @ Dallas :::: did not stop Iowa from traveling to Texas

Michigan and the SEC
Georgia - 1957 @ Ann Arbor and 1965 @ Ann Arbor :::: Michigan owes 2 trips to Athens
Kentucky - 1908 @ Ann Arbor :::: Michigan owes a return trip to Lexington
Missouri - 1955, 1959, 1969, and 1975 @ Ann Arbor :::: Michigan owes 4 trips to Columbia
South Carolina - 1980 @ Ann Arbor, 1985 @ Columbia (pre SEC H&H) :::: Shows UM knows how it is supposed to work
Texas A&M - 1970 and 1977 @ Ann Arbor :::: Michigans owes 2 trips to College Station
Vanderbilt - 1905, 1906, 1908, 1911, 1914, 1923, 1969, and 2006 @ Ann Arbor : 1907, 1913, and 1922 @ Nashville
(Michigan oves 5 trips to Nashville just to stand even with Vanderbilt)

Michigan State and the SEC
Kentucky - 1944 and 1946 in Lexington : 1945 and 1947 in East Lansing (MI ST was IND back then)
(shows Michigan State understands home and homes as an IND)
Mississippi State - 1928, 1946, and 1947 @ East Lansing : 1929 @ Jackson, MS :::: owes a few free trips to Starkville
Texas A&M - 1934 @ San Antonio, 1952 @ East Lansing, and 1959 @ East Lansing :::: owes College Station a trip

Minnesota and the SEC
Missouri - 8 games 1943, 1944, 1945, 1961, 1962, and 1965 @ Minneapolis : 1966 and 1970 @ Columbia
(looks like Mizzou is due 6 trips to level the numbers)
Vanderbilt - 1924, 1929, 1930, and 1959 @ Minneapolis :::: Gophers have not even played 1 trip back to Nashville
