The Boston Celtics have offered Jaylen Brown a four-year, $80 million deal, but the 22-year-old wingman is reportedly seeking more.

Chris Haynes laid out the details in his recent article for Yahoo Sports:

But even with history not on Brown’s side, the Celtics have extended the 6-foot-7 swingman an offer of four years and $80 million, league sources told Yahoo Sports.

But Brown believes in his ability to one day be a star and is pursuing a bigger offer, sources said. Next season the Celtics will have another major decision: figuring out if Jayson Tatum is worth the rookie-scale max.

The Celtics selected Brown with the third overall pick in the 2016 NBA Draft. He's eligible to sign a rookie extension up until the NBA's deadline, which falls on Oct. 21 at 6 p.m. ET. If he doesn't sign by then, he'll be a restricted free agent this summer.

In September, Brown noted that he isn't stressing over the situation:

“To be honest, I'm not putting too much thought into it,” Brown said in a September interview, referring to his contract negotiations with the Celtics. “I'm not losing any sleep over it. I think stuff like that will end up working itself out.”

Brown has become an important piece of Boston's rotation, so it will be interesting to see what sort of deal the two sides can work out in the end. There is no doubt Boston would like to keep him, but at what cost?
