I've seen this go roughly. A director who brings in a lot of new technical views, challenging the perspectives and opinions held by the team, might not have an easier time than a staff engineer. The director was largely right, but dealt not just with technical resistance but with more political fallout of having disgruntled employees reporting to them.
Forcing change isn't easy. It can pay well, when upper management knows someone needs to take on that role, and doesn't have anyone already doing it, but authority alone won't solve your problems. Especially if your management doesn't want to be seen as the bad guy themselves.
