He's a Leaf for life!
Most draft picks, especially #1 overalls usually stick it out with the team that drafted them. Auston is a great kid, who thinks about others (Sick Kids) and is well beyond his years. Of course, no one knows what the future holds but it's highly unlikely he leaves Toronto. We have a real management team made up of hockey greats, he has a great supporting cast around him (Rielly, Marner, Nylander, Hyman, Brown, Zaitsev, Dermott, etc) - it's a perfect situation.
If he decides to go anywhere, most likely it would be for his hometown team, Arizona. The good thing is, Arizona likely won't even have a team by the time he reaches UFA, if we even let him get that far. He'll bring his fellow Arizonian girlfriend Jordyn Johnsonn along to Toronto eventually and he'll be fine
