Anyone have data on Minnesota after their great run? Did they slowly fade or was it more of a collapse?
Minnesota is 263-324-5 since they won their last (shared) Big Ten title in 1967. Prior to that, their record was 431-194-36, with 18 Big Ten championships and 7 MNC's.
But, if you go back to 1941, Minnesota had 16 Big Ten championships and 6 MNC's. It's record was 306-94-25.
From 1942 through 1967 the record was 125-103-11, with 2 Big Ten championships and 1 MNC.
So, which is the inflection point? 1941, or 1967?
The Gophers were pretty mediocre for much of the 50s and 60s anyway.

In 1960, they were voted Number 1 because the Rose Bowl loss didn't count and they were 8-2.
So, the transition probably is closer to 1941, with a few up seasons thereafter. I'm not sure we can discern much from pre1941 results relevant today.
I was going to basically say what Badge already said. I'll expand on it a little bit.
The major inflection point is definitely WWII. When they won the 1941 NC is was their second in a row and fifth in eight years. NC's are a little bit fluky but using league titles as the gauge, the Gophers' league title in 1941 was their:
- second consecutive league title
- seventh league title in nine years
- 16th overall league title
The Gophers were a Charter Member of the league so they began competing in 1896. In the 46 seasons from 1896-1941 the Gophers won 16 titles. That is a little better than one every three years. From 1942-1967 they won two in two in 26 years that isn't nearly as good. Since then, obviously, they have none in 51 years which is even worse.
1960 and 1967 were both split titles. Minnesota shared the 1960 title with Iowa and they shared the 1967 title with Indiana and Purdue. They also had an OOC loss both years. In 1960 they lost to Washington in the Rose Bowl and in 1967 they lost 7-0 to the Cornhuskers in Lincoln. Also note that the Nebraska team that Minnesota lost to in 1967 was not part of Devaney/Osborne's glory days of Husker football. That team was 6-4 with losses to Kansas, Colorado, Mizzou, and Oklahoma.
Up through 1941 it was not unusual for Minnesota to go undefeated. From 1942 through 2018 their best ever seasons ended up 8-2 (1960, 61, 67), 10-3 (2003), and 9-4 (2016). In the last 77 years they best they have ever finished is two losses. They finished undefeated back-to-back the two years prior to that.
