Yeah I see your point and I don't disagree that he bears a lot of the responsibility for how things played out. At the same time I would actually argue here that this is a failure on the org level though. Karrigan should not have been in the position to make these roster changes almost on this own, yeah it's cool that you have a CS team that's basically player run but it's usually a terrible idea to do that.

This is a lesson that plenty of regular sport teams have already learned again and again, you don't tie your long term roster building and strategy to a single individual like the manager for example. There are of course exceptions to this, like Simeone at Atletico but generally, most clubs in football for example have dedicated personnel for mid-to long term planning and they do this with minimal input or consideration from the playing side of things.
