In the final AP Poll since 2020
2024- Purdue(2), Illinois(6)
2023- Purdue(3), Indiana(21)
2022- Purdue(10), Wisconsin(14), Iowa(16), Illinois(19)
2021- Illinois(2), Michigan(4), Ohio State(7), Iowa(8), Purdue(20)
2020- Michigan St(9), Maryland(12), Wisconsin(17), Ohio State(19), Illinois(21), Iowa(25)
Last 2 seasons... Not great. 2023 was the first time since the 2008-2009 season that the B1G only had 2 teams in the final AP Poll. Michigan St(8) and Purdue(17). 2012-2013 might be the best year for the top of the league as 4 teams finished in the Top 10. Indiana(4), Ohio State(7), Michigan St(9), Michigan(10). Also goes a long with the 2020-2021 season.
2025 as of now- Oregon(9), UCLA(15), Michigan St(18), Purdue(20), Illinois(22).
This is better than last year where at this point it was Purdue(1), Illinois(9), Wisconsin(21).
So all in all, yea the Big Ten was down the past couple years and this year is... Okayish but you added 4 teams and 2 of them suck.
