Jaylen Brown will head into the 2019-20 regular season with plenty of security as the Celtics agreed to a four-year deal with him worth up to $115 million with incentives hours ahead of the negotiation deadline on Monday afternoon, as first reported by Adrian Wojnarowski of ESPN.com.

Brown's new deal will begin in 2020-21 and is just $15 million short of a max contract over the length of the contract for a restricted free agent or $3.75 million per season. With incentives factored in, the deal will count $107 million against the cap according to Jay King, with another $8 million of possible earnings in unlikely incentives. Brown's agent Jason Glushon was spotted at the Auerbach Center on Monday afternoon, at which point he was putting the finishing touches on the agreement it appears. There will be no option years for either side in the deal, according to Yahoo Sports.

“(Jaylen's) a great person and hard worker who, at 22 years old, can score and defend against the best players in the NBA," Danny Ainge said after announcing the deal. "Jaylen is a true professional who did a great job accepting his role last season, and he is a major part of our championship goals.”

Brown, 22, enters his fourth NBA season with the Celtics, holding career averages of 11.2 points (46.2% FG, 35.5% 3-PT, 65.8% FT), 4.0 rebounds, 1.3 assists and 24.4 minutes over 222 career games (115 starts). The Marietta, GA native was named to the NBA’s All-Rookie Second Team in 2016-17, and has played in at least 70 games in each of his first three NBA seasons. In 44 career postseason games (24 starts), Brown has produced 12.1 points (47.6% FG, 36.0% 3-PT), 4.0 rebounds, and 1.1 assists in 24.4 minutes.

The rookie extension is the first Danny Ainge agreed to since 2009 with Rajon Rondo (five years, $55 million). Brown joins six other players from his 2016 draft class that agreed to extensions ahead of Monday's deadline. A full look at those deals:

Ben Simmons: Five years, $168 million
Jamal Murray: Five years, $168 million
Pascal Siakam: Four years, $130 million
Jaylen Brown: Four years, $115 million 
Buddy Hield: Four years, $94 million (up to $106 million with incentives) 
Domantas Sabonis: Four years, $77 million (up to $87 million with incentives)
Caris LaVert: Three years, $53 million

BSJ Analysis

This doesn't come as a huge shocker given how the fact that Gluschon was in the Celtics building on Monday but it signals a bit of a shift in the C's front office philosophy. I'll preface things by saying I expect there to be some incentive language in this deal so Brown's not fully guaranteed to get $115 million. That language should come out in the coming hours and days. However, consider most of this money (over $100 million) is
