Everyone makes bad decisions. People, organisations, govt, footy clubs.
When you do, you try to recognise them so you don't repeat them, even though they may arrive later in a different disguise.
Inconsistent performance, consistent injuries, dumping players who maybe you shouldn't have and keeping coaches you definitely shouldn't, and constantly struggling because of it, isn't a sign of constant bad luck, curses, Umps, Karma or Ch7 bias.
It's bad decisions, followed by bad decisions. Ad infinitum.
