He earned his first NHL camp invite in September, signed his first American Hockey League contract in October, and, after his first season of playing hockey in North America, returned to Europe to represent Denmark at the 2017 IIHF World Championship.
Not bad on all counts.
The latter, in particular is impressive.
"It's always a big honour," said Aagaard, who has represented Denmark at the IIHF World Under-18 Championship, the IIHF World Junior-A Challenge and the IIHF World Junior Championship and now twice at the World Championship level.
"Things ended too early in Stockton, so to come here and represent Denmark is an amazing feeling. It's always fun to play for your country and definitely a big honour.
"Any tournament you can play in and against these players is a really good tournament for me. It was a little different coming back and playing on the big ice. I was looking forward to coming back and getting a lot of ice time. I didn't get as much as I wanted to but it's a process.
"I'm young. It's a process and I took it step-by-step."
He's underselling it.
