It's very hard to build the perfect team from the get-go. However, you can probably build a pretty good team over time. In my opinion, it's better to make an average decision than no decision at all; you can improve from average to something better as you go along.
Yes but what tends to happen is - the risk is - youll probably just end up with a stable team, but not a good team. The best will have left or been pushed out. The ones that stay, desperate enough to be unethical to keep their positions, to lie to cover their asses. A barely functioning but stable entity floating in space not producing anything of value until the company slowly withers and disappears.
