It won't be a disaster as long as they're humble and willing to learn.
You can't shortcut these things.
For me as long as people have one or the other I can work with it. I've often been in scenarios with people that aren't good and won't collaborate and THAT'S the hell.
Obviously both is best but the skill set is rare. I'll happily take someone that defers to me and trusts my judgement over the HELL. Its not ideal and doesn't result in the best outcomes but its still workable.
