Oh for sure, he did good when it went sideways, and without him it might have gone horribly South instead. I'll definitely say I don't know where the line is. For me it's just highlighting the point that nothing is in isolation. Decisions have consequences, and sometimes, in hindsight (sadly rather than foresight enough to avoid entirely), we can judge the decisions to have been a bit off..or wildly off.
It's rare that something is truly just one person's problem. And on that day, in that set of circumstances, it was certainly more than one person's problem, which unfortunately could have actually been no-ones problem if different choices were made all round. That's kind of my base line point.
