NBA Insider: Jaylen Brown Contract Talks Are "Fragile"

By virtue of being named to an All-NBA team this season, Boston Celtics two-time All-Star Jaylen Brown is eligible for a five-year, $270 million supermax extension, and there are expectations all over the sport that he'll be offered it and will accept it. 
But hold the line, says ESPN's NBA Insider Brian Windhorst. 

Windy warns that these talks aren't so straightforward, and they may, in fact, be "fragile."

While talks are indeed ongoing with the 26-year-old Celtics star, Windhorst says "I think it’ll get done, but he’s eligible for up to 35% of the salary cap, but he doesn’t have to get that. The Celtics could negotiate on that. They could negotiate on a player option. They could negotiate on several things. So it’s not as simple as saying, ‘Jaylen, here’s your contract, sign it or not.'

"There's aspects within the deal that you gotta negotiate, so until it's done, it's not done!"

The Celtics, Windy points out, would be locked in, once the deal is signed, and unable to trade Brown for a full year. Not that they'd necessarily be looking to, but there have been rumors of his name being involved in other past superstar deals, most notably the Kevin Durant rumors last summer. 

And as we know, there are two superstars currently on the trade market, in Damian Lillard and James Harden. 

Brown made the All-NBA second team this season, averaging 26.6 points, 6.9 rebounds and 3.5 assists per game.
