As far as I'm concerned this isn't ISU's biggest bowl win ever (that's still the Fiesta Bowl against Oregon)... but this was still by far ISU's most successful season ever with its second biggest bowl win.
Beating #13 Miami in Florida, yeah it feels great and is big.
Lots of debate if this year or 2020 is better season. We were definitely closer to winning the Big 12 CCG in 2020 and finished outright first place before title game. Big 12 was maybe a little stronger league that year, but not drastically so. Currently Sagarin has Big 12 just an eyelash below Big Ten and clearly above ACC top to bottom, so the conference didn't fall off the map. In 2020 the team was 9-3 and the two cancelled games were Iowa and an FCS team, decent chance that team has same 11-3 record with comparable or better wins had non conf games all been played. Breece would have probably been just under 2000 rushing yards with those two games, he was the best offensive player in college football imho.
I could go either way, definitely don't want to look down at 11 wins for a team that had never had 10.
I REALLY don't understand people who somehow think playing only 12 games instead of 13 or 14 and not playing in front of full crowds makes a season completely illegitimate, locally I think some of that comes from people who like to diminish ISU. I like that they can't do that as easily now that we have another comparable season. As an NBA fan it also baffles me people want to discount the bubble championship (and I hate the Lakers), they locked the best players in the world up to focus on absolutely nothing but basketball, how could that possibly make them worse at basketball? NCAA hoops 2020 obviously didn't even have a tournament which is much different.
