The former second-round pick requested a trade last off-season before settling on a one-year deal, but was one of 11 players to file for arbitration this off-season after receiving a qualifying offer from the Leafs ahead of the June 30th deadline.
The relationship between the two sides has been tenuous at times, but the California native skated in a career-high 69 games last season before being scratched for all but three of the Leafs' playoff games.
The Leafs have almost $3M in cap space, so they would still be able to make a minor move or two after, but it will force the team to make a difficult decision. While Robertson's name continues to be in trade rumours, the Leafs will need help to produce offense without Mitch Marner, and Robertson has shown he can contribute.
At the same time, given his small size and inability to produce consistently, the Leafs may look to move him in favour of someone that has shown consistent production.
Anything can happen in an arbitration case, so we shouldn't exactly bank on that number being $1.5M. It could very well be higher or lower depending on how the case plays out.
