Nick Robertson decided to stick around with the Toronto Maple Leafs after a topsy-turvy off-season, but when asked about it, he refused to go into detail.
Nick Robertson Avoids Responding to Important Media Question

One of the major talking points this summer was Maple Leafs’ forward and pending RFA, Nick Robertson, requesting a trade out of the organization. After receiving his qualifying offer, Robertson was very quick with his request but general manager Brad Treliving never gave in.
There was certainly a lot of interest on the trade market for a former second round pick with RFA eligibility but the Maple Leafs saw a fit for the oft-injured forward.

Robertson eventually signed a one-year deal recently and is expected to battle for a top-9 role this year, however when asked about the situation, he refused to go into too much detail, according to David Alter’s tweet:
“I’m not going to deep dive into that. I signed in Toronto. I’m happy to be in Toronto. Being back here a week ago, it’s good to see everyone. I’m happy to be back.”

It’s certainly not a comfortable situation for a player to return to the scene of the crime, so to speak, and come back to training camp after signing a one-year deal with the same team you tried to get out from. However, Robertson’s quote at least shines a tiny light into his feelings towards the organization and that he’s glad to have the contract dispute solved, at the very least.
Robertson finally enjoyed an injury-free season last year but struggled with consistency and was often left a healthy scratch. He finished the year with 14 goals and 27 points in 56 contests and is expecting to bounce back from those numbers in a big way this year with the club needing help on the left-wing.
