And that's exactly what Darje has been saying since the start, he even went out and said the team lacks winners. He's said that they're not proactive and reactive, etc.
They've hired players like Burns and Ljujic who Darje believes has the attitude and desire, and he's also said he's working with other players (he specifically mentioned Ridenten) to instill that belief and desire into them.
It's not about being a realist or not, it's about seeing the good parts of life rather than bad. And your sarcastic remark shows just how miserable you are.
Not sure how sarcastic = miserable.
It's all in the context.
