Kevvie didn’t underachieve in one season. He was sacked because of his performance over 4 years. It wasn’t ruthless, it was inevitable.
Missing top 8 next year would be a massive failure. Demanding top 4 (not saying you are) because we’re bitter about Kev is being irrational.
We don’t know just how badly standards have dropped at the club or what state the culture has been left in. Kev also oversaw terrible roster management post-Ikin, which is another reason he got the ass.
Giving a coach “top 6 in your first season or else” targets leads to decisions that only care about short term success. I think Madge gets 2 seasons, almost no matter what, as should any coach.
My final point is that I think people focus too much on wins/losses and ladder position, without considering how a team plays. As an example, if we have top 4 defence, see obvious structures and significantly reduce errors but lose Reyno and Walsh for most the season then an 8th place can be something worth respecting
