Knies signed his ELC with the Leafs at the very end of the season, just in time to sneak into 3 regular season games and 7 playoff games prior to suffering a concussion, which halted his playoff run early. Since Knies had come straight from the University of Minnesota to Toronto, there was no time for him to secure a place of his own the GTA, so he decided to take up Tavares' offer to room with him for the duration of the season and playoffs. Needless to say, the rookie winger had a lot of great things to say about the experience.
Knies had mentioned at the end of the year that he had received a number of offers from various Leafs to come and live with them. In the end, the decision was an easy one for him to take Tavares up on his offer, given the Leafs captain's standing with the team and around the league. Tavares has a reputation of being a consummate pro and such a well-respected player, so you have to appreciate Knies being aware of that and wanting to take full advantage of living with and taking notes from one of the most consistent players of this era.
