The basics: 5-9”, 172lbs, played for Chaska High School & the Tri-City Storm last season.
Koster is a left handed defender who played high school hockey in Minnesota and a few games in the USHL as well. He’s committed to the University of Minnesota for the 2019-20 season. Over his high school career he’s scored 185 points in 95 games (1.95PPG) from the blue line. He doesn’t have a lot of international experience, only five games played at the Hlinka-Gretzky Cup.
State of Hockey held a Q&A with him and he’s already good at hockey answers:
State of Hockey: Who has had the biggest influence on your hockey career?
Mike Koster: My parents. They have made countless sacrifices to get me to practices, games, training sessions, workouts, etc.
SOH: Favorite hockey memory?
MK: Winning gold for Team USA at the Five Nations Tournament in the Czech Republic
SOH: Favorite NHL player?
MK: Erik Karlsson
SOH: Describe your game...
MK: I’m a small offensive defenseman with good hockey IQ and skating ability. I can make plays in transition and help by jumping into the rush
SOH: What’s the best advice you’ve received?
MK: No matter what happens, always stay humble and keep working hard.
Koster is really coming along…fresh off of a game that saw him get his first points in the USHL, Koster was playing with a lot of confidence
Koster showcased his playmaking ability in this game, often leading and joining the rush coming out of his own end.
Offensive defenseman who was not shy about jumping into the play. Even took a faceoff and played center for a shift.
Koster used his speed to breakdown the Czech defense, and against Finland he used his skating ability to generate plays as well.
Koster had an above-average two-way performance against Canada and once again showed a high-level transitional skillset. His mobility is impressive and he can generate a separating gear.
From The Hockey News’ Steven Ellis:
Toronto gets Michael Koster.— Steven Ellis (@StevenEllisTHN) June 22, 2019
He struggled with USA's Hlinka Gretzky team but he's a skilled defender with good offensive potential. He can move well, but he's not the fastest. #NHLdraft
