There was a lot of other stuff going on with that ship, especially persistant maintenance issues. Ship suffered a steering casualty which caused a breakaway during underway refueling.
From what I've read, the steering issues might not have necessarily been the captain's fault - they were apparently reported IAW standard protocol, a tech team was sent out, but the tech team were unable to isolate/diagnose the problem while the ship was in port, and the tech team didn't have authorization/budget to stay on the ship when it put back to sea.
So the ship went back out with the cause of the steering problem unsolved, and it kept happening.
IMHO, that's on Big Navy for not doing what was needed to address an issue that the captain had notified higher of IAW policy. Unless their position is that he should have refused to go out unless he could take the tech team along.
