Halsey's aggression and the limits of plausible replacements

How should Admiral Halsey's wartime command be judged against the officers who might have replaced him?

His aggression produced questionable decisions, but credible replacements also needed the seniority, experience, and institutional trust required for major fleet command.

Admiral William Halsey's aggressiveness is assessed as both useful for advancing operations and a cause of questionable decisions. Any criticism also has to consider which replacements had sufficient seniority and experience for his command. The British examples of Philip Vian and Robert Sherbrooke illustrate the same constraint: tactical ability did not confer the seniority or recognized experience required for larger formations. They are comparisons for the command problem, not proposed transfers into Halsey's post. A less experienced replacement could make worse mistakes, so tactical promise alone is insufficient grounds for judging a major fleet appointment.
