Dorian has had to trade away every player the fans liked and wanted, he is bashed the entire time around the city, that isn’t a task for the weak.
Dorion's response to the question about DJ being a "cheap hire" in the introduction press conf was proof enough (for me), that he is a beta trying to pass off as an alpha.
He's weak because he can't negotiate with other GMs, with star players and their agents, with the press. Anyone he goes toe to toe with on business, he comes out the wrong end and then fumbles out an unconvincing pat-on-the-back message to the media.
A strong minded person does not need to continually reassure the public that he's doing a good job, he promises, he even got a high five and a hug the other day.
