The "Indiana faced an easy schedule" trope is a bit disingenuous. Here are a few truths to illustrate my point:
1) While I despise SOS narratives and think it's the most over-emphasized metric in college football, do you know who finished with the #1 SOS in 2025-26? That was Indiana, and by a wide margin -> the gap between #1 SOS IU and #2 SOS Oregon was wider than the gap between #2 SOS Oregon and #5 SOS Miami.
2) The record for most Top 10 wins in a season is 7 by LSU in 2019. Only 2 other teams in CFB history beat 6 Top 10 teams -> 2024 Ohio State and 2025 Indiana.
3) Most people who know ball, recognize the schedule significance of facing your toughest opponents away from your home stadium. Only one of Indiana's six Top 10 wins came at home. This doesn't even include a pair of additional games played at two of the most challenging road environments in CFB: Kinnick Stadium vs. Iowa (SP+ #12 / FPI #16) and Beaver Stadium vs. Penn State (SP+ #15 / FPI #18).
4) Indiana played 8 games against teams in the SP+ Top 25, with only #20 Illinois being a home game. In fact, 10 of Indiana's opponents finished with a higher SP+ than Arkansas, Kentucky, Miss St, and Florida! Note South Carolina narrowly missed being a 5th SEC team on this list of lower SP+ ratings.
5) Let's talk about those out-of-conference G5 "cupcakes". Two of those opponents (Old Dominion and Kennesaw State) finished with 10 wins and went bowling. ODU's #49 FPI was significantly higher than Miss State's #58 FPI, and ODU's #50 SP+ was comparable to South Carolina's #49 SP+. Both of these teams were many levels higher competition than teams like 3-9 San Jose State, 2-10 UTEP, and 2-10 Sam Houston.
I really don't like the strength of conference arguments, and consider the SEC and B1G about the same in terms of difficulty. Hopefully this tired discussion point will die the death it deserves before next season starts.
