During Washington Capitals development camp in June, coach Todd Reirden called the 19-year-old prospect one of the Capitals' top two young defensemen, and director of player development Steve Richmond said the No. 31 pick in the 2018 NHL Draft could play in the NHL this season.
But Alexeyev vows he won't rest on such thoughts and praise.
"It's pretty special," Alexeyev said at camp. "I should be proud of myself, but I still have to work hard. It doesn't mean I can calm down. Still have to work hard, get better every day, get stronger, and try to be the best."
Alexeyev's story nearly took a dark turn in March when he was taken off the ice on a stretcher following a knee-on-knee collision playing for Red Deer in the Western Hockey League.
"I was sitting right here, and it happened across the ice and I thought for sure it was gone," Richmond said of Alexeyev's left knee. "I thought it was lights out for him. It was pretty scary."
Alexeyev ended up in a knee brace and his stellar season was over. He finished with 43 points (10 goals, 33 assists) in 49 games as a top-two defenseman, and has 101 points (21 goals, 80 assists) in 135 games in three WHL seasons.
After rehabbing off the ice with Hershey of the American Hockey League, Alexeyev returned to his home in St. Petersburg, Russia, where he began skating about three weeks before development camp.
