Koenig averaged 16 points and 11 rebounds for undefeated state champion Fargo North this past season and he is also an All-State wide receiver.
Koenig is the third player to commit to Wisconsin Green Bay under first year head coach Tod Kowalczyk. The Phoenix previously got commitments from 6-4 shooting guard Adrian Schaffer from Rochester (MI) Adams and 6-7 small forward Josh Lawrence of Ashton (IL) High.
Wisconsin Green Bay finished 9-21 last season, their third straight losing season. However, hopes are high this season as they move into the new 10,000 seat Resch Center.
