Easy to respond to cliches with other cliches. For example, this one: too many cooks in the kitchen spoils the broth.
I think the concern about how to fit Zo in that
@OriginalCanesCanesCanes brings up is valid. While I'd love to have Zo in a contributing role on this team and think he would bring a lot of value, adding talent for the sake of adding talent - especially at the top of the pyramid - isn't always a good idea. That's where the executive decisionmaking happens, and the more of those types of personalities you have in the room the more likely it is there will be conflict. Conflict isn't bad in and of itself, it can hone decisionmaking and force stubborn people to see different points of view. It can also cause the org to be pulled in too many different directions when ambitious and accomplished people have different visions. There's a reason companies almost always have one CEO and it ain't because they're not able to find enough high caliber talent.
This makes sense from Mario's perspective - he's a talent evaluator too, a **** good one, and as the HFC he will have a vision for the team and how the players fit in. A dynamic where he's potentially getting challenged or second guessed by someone whose position in the chain of command isn't well defined, or is well defined but the person carries significant respect and weight in the org, puts him in a difficult position. It might be easier for him to fill that role with an outsider rather than someone like Zo who is so central to the U family. It also makes sense from Zo's perspective - the guy is going to want a position where he has the ability to contribute in a meaningful way, where his expertise is respected and he feels comfortable disagreeing without causing internal strife. It might be easier for him to find that at a place where there's not such strong emotional ties and already a clearly defined role for him in the org structure.
Without hard info we're all just speculating at this point. I hope they figure it out; I finally feel like I trust the guys behind the wheel enough to think that they will. Just making the point that it doesn't really make sense to make a decision of this magnitude based off of cliches or analogizing to recruiting players for a college football team.
