That was me and he is. Pompous as they come. Could be an age and money thing, though. The handful of times I ever had interaction with him, which was his rookie year, he thought he was the ****, all the while, Domingue, Duclair, OEL and Schenn were as humble as ever.
To break it down, in a better perspective, he wasnt tolerated very well with more than a handful of players. He and Chychrun became boys after Chychrun arrived with nowhere to go, hence why he lived with Domi. I am not sure if you all are followers of these guys on social media, but you wont see a whole lot of player interaction when it comes to Domi like you do the other guys. Duclair had a similar problem, but without the "I am better than you" attitude. As with everything though, things and people change and this was a few years ago, so who knows. But, I am sure we have all worked with and or had friends that thought they were better than anyone in all aspects and I am sure, like most, we weren't real fond of.
I am not going to try and convince you Domi was one way or another, but you can create your own guess as to why he was shown the door, or wanted that "fresh start."
Welcome aboard Galchenyuk.
