What a native German speaker would actually say
“Unberechenbar” means hard to predict. The English phrase also suggests a risk to other people, so keep that risk clear in the sentence.
“Risikofaktor” can suit a discussion about a team, but sounds impersonal when applied to a person. It is stronger than simply calling someone independent.
