Jayson Tatum is getting paid.

The Boston Celtics forward agreed to a five-year, $314 million contract extension, according to ESPN's Adrian Wojnarowski, on Monday. 

Tatum, who helped lead the Celtics to their 18th NBA championship in June, averaged 26.9 points and 8.1 rebounds per game during the regular season. He is one of six Celtics players to make at least three straight All-NBA first teams, and the first since Larry Bird, according to ESPN Stats & Information.

Tatum's deal surpasses that of his teammate Jaylen Brown for the largest contract in NBA history. Here's how the contract stacks up with others throughout sports.

Jayson Tatum, Boston Celtics: 5 years, $314 million

The first player to earn $70 million in a single season, Tatum has 2,711 career playoff points, the most by a player age 26 or younger in NBA history, according to ESPN Stats & Information. He averaged 25 points per game during the Celtics' championship run in 2024. 

Jaylen Brown, Boston Celtics: 5 years, $304 million

Year signed: 2023

Brown averaged 23.0 points per game last season and alongside Tatum helped lead the Celtics to their 18th NBA championship.

Nikola Jokic, Denver Nuggets: 5 years, $272 million

Year signed: 2022

The reigning NBA MVP, Jokic signed a max extension with the Nuggets in 2022 that, until Brown's deal, was the largest contract in NBA history.

Bradley Beal, Washington Wizards: 5 years, $251 million

Year signed: 2022

After declining an option to become a free agent in 2022, Beal signed a max contract to remain with the Wizards for the next five seasons. His time in Washington under the extension proved short-lived, however, as he was dealt to the Phoenix Suns last offseason.

Giannis Antetokounmpo, Milwaukee Bucks: 5 years, $228.2 million

Year signed: 2021

At the time, this was the largest contract in NBA history, but it was well worth it for the Bucks. Antetokounmpo led them to a title and was named Finals MVP in 2020-21. He's only gotten better since then and averaged over 30 points per game in back-to-back seasons for the first time in his career.

Trevor Lawrence, Jacksonville Jaguars: 5 years, $275 million (72.7% of total contract)

Year signed: 2024

Lawrence led the Jaguars to an 8-8 record in the 2023 season and threw for 21 touchdowns, the second most of his career so far. His contract has $200 million guaranteed.

Joe Burrow, Cincinnati Bengals: 5 years, $275 million (79.6% of total contract)

Year signed: 2023

Burrow led the Bengals to a 12-4 record in 2022-23. He threw for 35 touchdowns to go with 12 interceptions, passed for 4475 yards and completed 68.3% of his passes along the way. His contract has $219 million guaranteed.

Nick Bosa, San Francisco 49ers: 5 years, $170 million (72.1% of total contract)

Year signed: 2023

Bosa earned the Defensive Player of the Year award, his first All-Pro selection and third Pro Bowl berth by posting a league-leading 18.5 sacks, 51 tackles, two forced fumbles and 58 quarterback pressures (third in the NFL) the season prior to signing his big deal.

His contract includes 122.5 million guaranteed, making him the highest-paid non-quarterback in NFL history. His brother, Joey Bosa, holds the No.2 spot among highest paid defenders (by total guaranteed money) with a $102 million contract.

Justin Herbert, Los Angeles Chargers: 5 years, $262.5 million (83.3% of total contract)

Year signed: 2023

Herbert was selected with the sixth overall pick in 2020, and in the 2022 season, he led the Chargers to their first playoff appearance in four years.

His 14,089 passing yards and 1,316 career passes are the most through a quarterback's first three NFL seasons. He was slated to play on the fourth year of his rookie deal for $4.23 million. Instead, his average annual salary jumped up to $52.5 million, the highest in NFL history. 

Lamar Jackson, Baltimore Ravens: 5 years, $260 million (71.1% of total contract)

Year signed: 2023

Jackson was the second unanimous selection as NFL MVP in his first full season. He represented himself in contract negotiations, which went on for 27 months.

Jalen Hurts, Philadelphia Eagles: 5 years, $255 million (70.3% of total contract)

Year signed: 2023

Hurts, who led the Eagles to a Super Bowl LVII berth, threw for 3,701 yards with 22 touchdowns and rushed for 760 yards and 13 scores.

He was lined up to play the final year of his rookie deal, which included a base salary of $4.2 million. His extension, which includes the first no-trade clause in franchise history, will be about $51 million per year.

Deshaun Watson, Cleveland Browns: 5 years, $230 million (100% of total contract)

Year signed: 2022

Watson's contract is one of the largest in NFL history, but his tenure with the Browns has been marred by an 11-game suspension for violating the NFL's personal conduct policy by committing sexual assault, as defined by the league. He threw for 7 touchdowns against 5 interceptions in six 2022 starts.

Shohei Ohtani, Los Angeles Dodgers: 10 years, $700 million

Year signed: 2023

Entering free agency, Ohtani's market ranged from $500 to $600 million. The Dodgers hit it out of the park with their offer for arguably baseball's best player. Ohtani will not pitch in the upcoming season because of an elbow injury, but will likely be in the mix to make the playoffs for the first time in his career. 

Mike Trout, Los Angeles Angels: 12 years, $426.5 million

Year signed: 2019

Trout has been either the best player in baseball or close to it for the better part of a decade, and the Angels rewarded him accordingly. At the time he signed this deal, it was the richest contract in professional American sports. Though he's been hampered by injuries, he played 453 games (and counting) and won the 2019 MVP since the signing.

Mookie Betts, Los Angeles Dodgers: 12 years, $365 million

Year signed: 2021

The Dodgers secured Betts until the 2030s shortly after acquiring him in a trade from the Boston Red Sox. He's had two top-five MVP finishes and a World Series win since then.

Aaron Judge, New York Yankees: 9 years, $360 million

Year signed: 2022

The Yankees ensured their 6-foot-7 MVP slugger remained in pinstripes after he mashed an American League-record 62 homers while hitting .311/.425/.686 with an AL-leading 131 RBIs in 2022.

Francisco Lindor, New York Mets: 10 years, $341 million

Year signed: 2021

The Mets signed Lindor to this monster deal shortly before Opening Day 2021, and though he had a disappointing performance that season, he rebounded nicely in 2022 as the team won 101 games. Lindor hit a home run in the postseason, but the Mets fell to the Padres 2-1 in their National League wild-card series.

Fernando Tatis Jr., San Diego Padres: 14 years, $340 million

Year signed: 2021

Tatis had a huge season after signing his contract, hitting a league-leading 42 home runs and putting up 6.6 WAR in 2021. Injuries and a suspension for performance-enhancing drugs caused him to miss the entirety of the 2022 campaign, however.

Shea Weber, Nashville Predators: 14 years, $110 million

Year signed: 2012

This is a bit of an odd situation -- despite a distinguished career and five years remaining on his lengthy contract, Weber has been plagued by injuries and hasn't played since the 2020-21 season. It's quite possible that he'll never play in the NHL again.

Sidney Crosby, Pittsburgh Penguins: 12 years, $104.4 million

Year signed: 2013

Sid the Kid won't be a free agent until his age-38 season, but he's still producing for the Penguins. He was 10th in the league in points in 2021-22 and ended 2022-23 in 16th.

Connor McDavid, Edmonton Oilers: 8 years, $100 million

Year signed: 2018

McDavid hasn't led the Oilers to a Stanley Cup win yet, falling short to the Florida Panthers in 2024. But, he's one of just two players to unanimously win the Hart Memorial Trophy, doing so in 2021. The other unanimous winner? Wayne Gretzky.
