As the “leader” of the team say something like “I’m the head coach of this team, I didn’t perform up to our high standards. This loss is 100% on me. I’m sorry to my players, I’m sorry to my coaches. I will work tirelessly to not just learn from this but to be better for the team and the fans.” Even if it wasn’t specifically his fault, that’s what leaders do and say.
This is where his boring, cliche based communication style really does him a disservice. It comes across as disingenuous and fake.
