The Toronto Maple Leafs' roster may require more than mere tinkering according to TSN's Darren Dreger; significant pieces are needed to compete for the Stanley Cup. The focus is on acquiring heavier players, potentially using funds from Mitch Marner's contract should they choose not to renew it. The internal competition among star players like Auston Matthews and William Nylander could also impact team culture as they push for playoff success. Dreger notes that while Marner's departure isn't a certainty, there's a strong desire for change from both Marner and the team.
