Blaming your teammates might be accurate. It’s still not useful.

Two things can be true at once: they did let you down, and saying so changes nothing about the result. Accuracy and usefulness are separate tests, and blame only ever passes the first. Once the responsibility sits somewhere else, so does your ability to do anything about it, which is a poor trade for the small satisfaction of being right.

After the next thing that goes wrong, spend two minutes on your own part and skip the rest. Ask what you would do differently with the same unreliable people, since that is the only version you control.
