No, of course not. But it is an indicator....
Someone who signs up to be an aviator, and is fortunate enough to be selected and graduate training is expected to enjoy their job and get really good at it. When someone appears more interested in box checking, visibility, and staff opportunities at the expense of what most of us believe should be their focus, it reeks of careerist douchebaggery.
However, practical leadership for us in the USAF is usually quite limited (especially compared to other services) until FGO levels. Some guys do well, some don't, but the guys with several ops tours usually have more credibility and an ops focus, both of which usually equal "great commander" in our minds.
I know plenty of great leaders with zero hours. But I'm wary of an O5 with 1200 hours and 6 years at the pentagon.
