It's a hypothetical that's only meaningful at all if it's an all-or-nothing deal. If it was anything else, it would essentially just be normal hiring and therefore boring.
Understood, but I also would think finding an 'all-or-nothing' deal for a team of any real size would be somewhat unique at that point. If you have a team of 10, and all 10 are required to come along, there is likely some chance of redundancy unless we're talking about pure greenfield projects and buyers with no staff.
