> So either they are completely incompetent or the decision didn't matter much.
Or the field always wins. Every year a large team of highly paid professionals is responsible for selecting the best professional sports prospects to join their team. The team that goes first (almost) never gets the best player. Its not because they're incompetent. And its not because the decision doesn't matter- these are multi billion dollar organizations, and the decision is very much a high leverage one that will directly impact their fortunes.
Sometimes finding the best path is extremely difficult. Sometimes even when someone does see the best path, its still hard to recognize it as such. So I don't think its surprising at all for the best idea to come from outside a team devoted to solving a problem. Especially in today's age when more people than ever can propose solutions and more people than ever can see those proposals and bubble up the ones that sound good to them.
