Bokk describes himself as a skilled forward that likes to make plays and shoot the puck. He also says he's a good skater.
Last season, Bokk - a native of Schweinfurt, Germany - played in 35 games with Vaxjo Jr., scoring 14 goals and 27 assists (41 points). Due to injuries, Bokk was also called up to the Swedish Elite League, where he played in 15 games, scoring one goal and one assist.
"Of course you play against pros (in the Swedish Elite League) and they're stronger on the ice and off the ice," Bokk said. "They really guided me through practices and what I can do better."
According to NBC Sports Network, Bokk is the highest ranked German-born prospect since Edmonton's Leon Draisaitl in 2014.
"Once he settled into the U-20 League, he really took off," Armstrong said. "The clincher for us was when we went to see him in the playoffs right at the end. He was dynamic. We walked out saying 'Hey listen, if we get a shot at this guy, this would be a home run.'"
Bokk, whose mother and father traveled from Germany to join him at Friday's NHL Draft, said he couldn't be happier to be a Blue.
"It's a dream come true," he said. "It's great for every player to get picked at the NHL Draft. It's awesome, and just a great feeling.
"To get picked by the Blues, I'm really excited about what's going to happen."
