Looking at tournament results, these are the only teams other than PSU that have finished within 30 points of first place:
2023 none
2022 none
2021 Iowa (won)
2019 none
2018 tOSU
2017 none
2016 OSU
2015 tOSU (won), Iowa, Edinboro, Missouri
2014 Minnesota, OSU
2013 OSU, Minnesota
So a total of 11 teams in 10 tournaments, 7 outside of the year PSU tanked.
Looks like OSU is the only team that made the list 3 times.
