I'm usually one of the last people to want to fire a coach, and one of the last to squarely place blame on a coach, but it's really tough to find anywhere else to place the blame. 0-3 coming off of bye weeks, 0-4 if you count the bowl prep like a bye, 0-5 if you count the first game of the year prep like a bye. It's basically impossible to not place that blame squarely on coaching. Normally, you'd look at a schedule and feel good about any game where a team is coming out of a bye week, and for the 2019 Canes it was the complete opposite. The same issues, whatever those issues were, kept occurring and the coaches, including Diaz, had no idea how to correct them.
I don't think firing Manny, at this point, would necessarily be the right move, but he better find some coaches who can make an immediate difference. I think his being a first year HC was glaring. I don't think he's stubborn in the way Golden and Richt were. I think he badly wants to make it work here and will make tough decisions and do his best to be successful. I'm just not sure his best is going to be good enough.
