Nick Alberga of theleafsnation.com thinks the Maple Leafs will attempt to bring in one or two PTO players as several free agents remain on the market. Typically, when a player is signed to a PTO, they will attempt to show the team that they can play at their level which will award them a one-year contract.
According to Puck Pedia.com, there are several prominent unrestricted free agents who could help the Maple Leafs in the future which includes Kevin Labanc, Blake Wheeler, James van Riemsdyk, Kailer Yamamoto and Filip Zadina.
