yes but if he "fixes" them for 2 years only to win 1 year and then leaves and they regress into even bigger hole then they're in now then it's not something that's worth it really. It would be more productive to try and sort it out without him. Look at Red Bull now. As soon as Newey stepped back even for a little the team is nowhere and aero guys seemingly have no clue how to fix the car. I don't want Newey geinus reorganization in ferrari if that organization is depending only on him and is made to maximise his time results. The guy is old now let's say he gets sick, what will we do then if everything is on him. It's not good
I've been in positions where I had teams basically heavily depending on one brilliant individual to deliver the value and it always was awesome at first and ended badly.
