There's the possibility that his education situation could have an influence on his return. I understand that he's currently enrolled in an Engineering program at Western, and his hockey was a somewhat secondary preoccupation. He could come back to get his degree, while still playing for the Knights, and then graduate to the NHL with the bonus of an Engineering degree in hand. Not too many OHL players exhibit higher academic performances while actively devoting time to hockey. Back in the day, Dave Simpson managed to get his MBA degree while playing for the Knights.
