I came across the following tweet addressing Jess Myer's preview of our hockey team for The Athletic. https://twitter.com/harryorin/status/1046950862755651585 I didn't pick up on it when I initially casually read through the preview. However, as I reread it following the above tweet, "Hawks" is mentioned repeatedly, though Myers also uses "North Dakota". Is this a subtle troll or is this an overly sensitive tweet from someone who needs to accept the nickname and move on?
