I'm not surprised by the vote, but I will say that it was probably a tough decision for most of us.
If you asked this question before 2018, Barnett probably wins by the margin that Fitz won. Before this year, I'd probably still lean Barnett slightly.
I think the past 3 years are why Fitz is probably ahead for those that voted for him now, which includes me.
Yes there is recency bias at play to the extent that 2018-2020 just happened compared to 1995-1996 which is 25 years ago. But I don't think that is an overwhelming consideration here.
Since 2018 we have 2 Big Ten West titles, 2 more ranked finishes including #10 in both polls this year, and 2 high quality bowl wins (Citrus against Auburn and Holiday against Pac-12 South champion Utah).
If you add 2018 and 2020 to the sum before that from Fitz's first 12 years: the 3 10-win seasons, 3 ranked finishes, 3 bowl wins in 8 bowl appearances; it's enough to give the edge to Fitz now.
The Big Ten title issue is tough. Obviously we're in a 14 team Big Ten now with a championship game so it's hard to compare with 1995-2000 championships of the then 11 team Big Ten which each have different weights.
I would say outright division titles (like 2018/2020) are comparable to shared Big Ten titles (like 1996/2000), but the championship result and bowl game and its result also matter. There's a lot to weigh.
One final factor that favors Fitz but shouldn't is we all expect to win a Big Ten title at some point as long as he keeps putting together teams like 2018 and 2020 that are good enough to have a decent chance of beating a team like Ohio State. Once we do win a title, this debate will be moot in my opinion.
