Team, rank when played, final rank, record
(NR- not ranked)
2016 OSU - #2, #6, 11-2
2016 Wisky- #6, #9, 11-3
2017 Iowa- NR, NR, 8-5
2018 Iowa- NR, #25/NR, 9-4
2019 Iowa- #17/18, #15, 10-3
2019 Michigan- #16, #18/19, 9-4
2021 Wisky- #18/17, NR, 9-4
2021 Auburn- #23, NR, 6-7
2022 Purdue- NR, currently 5-3
So, only 2 top 10 teams- both 6 years ago.
Considering 2017 Iowa, 2021 Wisky, 2021 Auburn were not ranked at the end of the year and 2018 Iowa was only #25 in 1 poll and not ranked in the other, I’d hardly put them up in the annals of big wins.
