Jalen Brunson was among the first to respond to Mitchell Robinson's farewell message on social media.

Brunson wrote, 'Love you my guy! ☝🏾,' after Robinson agreed to a three-year, $47.4 million contract with the Boston Celtics.

What happened?

The New York Knicks were unable to match the Celtics' offer due to salary cap constraints, according to SNY's Ian Begley.

The decision was driven by the salary cap, with the Knicks prioritizing payroll flexibility throughout free agency.

Why it matters for Jalen Brunson

Robinson's departure marks the end of an era for the Knicks, who selected him in the second round of the 2018 NBA Draft.

Jalen Brunson, the face of the Knicks' title team, will now be part of a new era without Robinson.

What comes next?

The Knicks will need to adjust their lineup without Robinson, who developed into one of the league's premier offensive rebounders and interior defenders.

Deuce McBride, who now becomes the Knicks' longest-tenured player, shared a GIF from Toy Story of Woody saying, 'So long, partner.'

Robinson responded directly to Mikal Bridges, saying 'ima miss you bro ❤️.'

The reactions from the Knicks players reflected the closeness of the team's locker room.

Josh Hart called Robinson a brother, while Karl-Anthony Towns replied with a tearful emoji.

The Knicks' financial strategy was a key factor in Robinson's departure, with the team prioritizing payroll flexibility.

On Wednesday, Robinson broke his silence after agreeing to the contract with the Celtics, posting an emotional message to Knicks fans on Instagram.

'Life's a climb. But the view's great,' Robinson wrote.

The message resonated quickly, drawing thousands of reactions from fans and teammates alike.

Robinson's departure is a significant loss for the Knicks, who will need to find a new center to replace him.

The team's payroll flexibility will be crucial in the upcoming season, as they look to make moves to replace Robinson.

And so, the Knicks will move forward without Robinson, who will now be playing for the Celtics.

But the memories of his time with the Knicks will remain, and his teammates will always cherish the time they had with him.

So, the next chapter begins for Robinson in Boston, and the Knicks will need to adjust to life without him.
