Baby steps. Note Charlie was 6-6 and Herman 6-6 in their first seasons.
Sure but the context of those seasons is different. We didn't just go 6-7, 5-7, 5-7, we just went 10-4, 8-5, 7-3 (probably 10-3 without the cancelled games). We're 4-3 after 7 games, after starting 6-1, 5-2, 5-2.
Herman was 7-6 coming off of 3 losing seasonsm and we were right there in 5 of the 6 of the losses instead of getting stomped repeatedly. After 7 straight seasons of getting blown out at least twice per year, we lost only 1 blowout in 4 years. In other words, it wasn't a great season by any means but there was noticeable improvement from the very beginning.
Earlier this year we were down 33-7, i.e. 26 points, to Arkansas. In 4 years with Herman we never once trailed by that much (after his first season we only even trailed by 20+ once). We've now blown 21 and 14 point leads in back to back weeks. In the previous 4 seasons we never blew a lead of more than 10. We're 0-3 against the 3 good teams we've played. In other words, we aren't any better than we already were.
I'm not saying fire the guy after half a season obviously, just that we need to stop comparing the purported "bare cupboard" to how little we had to work with after the shambles of 2014-2016. Herman's on-field results were certainly mixed, but they aren't primarily what got him kicked out of here. We should, at the very least, be no worse this year than last.
