Saying "a star can't do it without a team" is very silly. That's like saying "well, sure but Shakespeare couldn't have written anything with a pen". True at some level, but I think we both know in that equation whether the pen or the man was more valuable. The point is that teams are necessary, but in many cases, are easier to come by than stars. Engineering stars do exist. Not all are loose cannons, like in popular culture. Some just do great work that others can't.
