Yeah, my first thought was a clear lack of stoicism. Accepting the hard things and enduring forward fast because a Captain must. Everyone is depending on that. I can imagine this guy trying his hardest and then just breaks; blanks out, freezes up, is overwhelmed by what has happened and what is happening, instead of only thinking about what’s coming next, which is what Captain’s have to do and actually do.

The logical Captain performs well from remaining cool. The emotional Captain performs well by being selfless above all. He is clearly neither if something is personally impacting him.

To simplify, this guy would be good if he were more Vulcan.
