BOSTON – The 2019-20 Boston Celtics season tips off tomorrow night, and there will be one less headache that the team needs to worry about thanks to some last-minute off-season contract negotiations.

According to ESPN's Adrian Wojnarowski, Boston Celtics small forward Jaylen Brown has agreed to a four-year contract extension worth $115 million with the club. The news came straight from the mouth of Brown's agent, Jason Glushon. Brown and Glushon have to be pleased that they managed to wrangle this deal out of the Celtics front office.

The 22-year-old Brown now becomes the first Celtic signed to a rookie extension deal since Celtics general manager Danny Ainge did the same ten years ago for point guard Rajon Rondo. Hopefully, Brown's future in Boston is more extensive than Rondo's, as long as he proves he is worth the investment.

The negotiations between Brown and the Celtics had been ongoing for some time now. Many insiders believed that Brown was going to defer from any offers from Boston and instead opt to play his way into a bigger contract in the 2020 off-season. Just last week, it was reported that Brown had denied a four-year extension with the team that would be worth eighty million dollars instead. Obviously, 115 million is a big upgrade and it is one that Brown has to be happy with.

For the Celtics, that answer is much more obfuscated. Brown is a top young talent in the game right now, but he is currently still the fourth best option in the Celtics' rotation. Is that a player who is worth almost twenty-nine million dollars annually? In the era of ballooning contracts for NBA stars, perhaps Brown slots into the figures better than expected. But unless he really makes the leap during the 2019-20 season, which, granted, I believe he will do, then the Celtics are hanging a lot of money on a player who is a perennial "solid role player" instead of a legitimate All-Star contender.

At the very least, Boston will now have peace of mind regarding Brown's immediate future in the league. And while there is no denying that this is an overpay (no shade is intended to be thrown at Brown. By all means, go secure that money, Jaylen), it could prove to be a bargain if the dominoes fall in the way Ainge is betting on.
