Because leadership isn't premised upon past accomplishments. Do you want a medal? I'll give a hundred medals - all the commendations you could possibly want - any other title you might desire - whatever brief you wish. Take a Star Destroyer. Take a Dreadnought. Carve out your own portfolio. Use your considerable talents in the service of the Order however you best see fit. But the ability to murder someone in a lightsaber duel bears no relationship whatsoever to the skills required to govern a galaxy.
I've been at this since I was five years old. Try to step over me. I'll cut your fucking legs off.
