Also 6-12 versus Cornell.
It’s worth mentioning that 10 of those 23 wins against the SEC were against Vanderbilt.
Anyway, I’m a bit confused on where you’re getting your numbers for 23-5-1 against the SEC.
The losses are fairly easy:
1 loss to Alabama
1 loss to Auburn
1 loss to Georgia
1 loss to South Carolina
1 loss to Tennessee
That gives us 5 losses, which is consistent with your claims (although I don’t feel it is accurate.)
Michigan has tied Vanderbilt once, which is consistent with your 1 tie.
Wins though, I’m a bit confused.
2 wins versus Alabama
1 win versus Arkansas
1 win versus Auburn
2 wins versus Florida
1 win versus Georgia
1 win versus Kentucky
1 win versus Mississippi
10 wins versus Vanderbilt
That gives us 19. Well, I have an idea as to where you’re getting your other wins.
Michigan is 3-0 against Tulane and 1-0 against Georgia Tech, two teams that USED to be in the SEC. I’ll give you the win over Tech, Tech was in the SEC when Michigan beat them, so that’s a fair claim that it was a win over an SEC team (though it’s mega cheesy, it was in the 1930s for god’s sake.)
However, not so fast on the 3-0 against Tulane, only one of those wins came while Tulane was in the SEC. Michigan beat Tulane in 1920, 1953, and 1972. In 1920, the SEC was still 13 years from existing, in 1972, Tulane hadn’t been in the SEC in something like 6 years. 1953 was the only year Michigan beat Tulane as an SEC member.
That would bring us to 21-5-1, since in fairness I don’t think we can count two wins over a team that was clearly not a member of the SEC ('21 Tulane and '72 Tulane.) At the same time, I’m not sure how you can count the win over South Carolina, since it happened before South Carolina entered the SEC. Also in fairness, the one loss to South Carolina came when South Carolina was not in the SEC. So Michigan’s record against SEC teams, from what I can see, is actually 20-4-1. (Note that this is fewer wins but actually a higher winning percentage versus the SEC than your claim of 23-5-1.)
Still, it’s worth noting that Michigan has only beaten an SEC team 20 times in its history, and that half of those wins were against Vanderbilt.
I could be wrong though, I’m just going from College Football Data Warehouse and easily could have miscounted, I’ll be happy being corrected if that’s the case :).
