If Boston Celtics wing Jaylen Brown makes an All-NBA team this spring, he will become eligible to sign a four-year supermax extension with the Celtics over the summer.

The contract would start at 35% of the 2024/2025 salary cap, and include 8% annual raises.

However, if he doesn’t make an all-NBA team, the Celtics’ options are far more limited.

Under the current NBA collective bargaining agreement (CBA), teams can offer players no more than 120% of their previous salary, or 120% of the estimated average salary – whichever is a higher amount.

Brown will make $30.7M in the last year of his current contract, so the Celtics can offer him no more than $36.9M starting out if he doesn’t make the all-NBA team.

The four-year total would amount to around $165M, tens of millions of dollars less than he would be able to make as a free agent.

But the NBA and NBPA are negotiating a new CBA, which could kick in over the summer and would make an extension far more plausible for Brown.

The new CBA would allow teams to offer 140% or 150% of a player’s previous salary as the starting salary for a new extension. Then the Celtics could offer brown a full max or near-max extension, depending on ’24-’25 salary caps.

Brown could earn an estimated $244M under the new CBA, or $181M with any other team. It’s a far better prospect than the current CBA.

Brown has declined to say what his plans are for the near future, saying, “I don’t know. As long as I’m needed. It’s not up to me. We’ll see how they feel about me over time and I feel about them over time. Hopefully, whatever it is, it makes sense. But I will stay where I’m wanted. I will stay where I’m needed and treated correct.”
