The Maple Leafs have been connected to Ristolainen in the past, so it would not too surprising if they had him on their radar. The Maple Leafs need to improve the right side of their defense, and bringing in Ristolainen would help things on that front. Furthermore, Ristolainen is signed beyond this season, so the Maple Leafs could bring him in even if they are not holding a playoff spot right now.Â
