Rather sanctimonious take there.
Robertson's stock skycrocketed in his draft plus one year and the Leafs management hoped to accelerate his path to the NHL by giving him top 6 duties in the 2020 bubble playoff series a la Logan Stankoven in Dallas this year, but he wasn't exactly ready and circumstances were difficult.
Between 2021 and 2023, he suffered a knee injury, a broken leg and a season ending shoulder injury from a routine Matt Roy hit and missed a ton of developmental time, NHL spot duty and wasn't much of an option for the Leafs.
Fast forward to 2024, Robertson is 23 and shows some flashes of production, but is otherwise utilized as a young 13th forward on an ELC, shuttled between AHL and NHL duty.
So looking back on this brief history, it's hard to see where the Leafs did this guy wrong other than accelerate the initial promotion which led to some accelerated expectations, plus a series of massive injury setbacks and lost time.
Ideally, the partnership between a team and player is a virtuous cycle of investment and growth and mutually beneficial: player flourishes and becomes a contributing member of a successful team. When you say a player doesn't owe a team anything, that's fine, but why would an organization need to do anything to accommodate if it's not good for the team?
Accusations of the team and fanbase being "toxic" by an outsider is meaningless, especially when they have ulterior motives like wanting to acquire Robertson for pennies on the dollar.
