Jayson Tatum has made himself even richer during the offseason, as the Boston Celtics star reached an agreement with the organization for a five-year max extension. 

ESPN's Adrian Wojnarowski reported the news and also stated that Tatum gets the full designated rookie max extension, and if he makes an All-NBA team that'll take it near $200M.

At only 22 years-old, Tatum has established himself as one of the best scorers in the league. 'JT' has a breakout season with the Celtics, being able to make the All-Star team and averaging 23.4 points per game. He also led the Celtics to the Eastern Conference Finals, where they lost to the Miami Heat in a five-game series. 

This great run for the third-year player came after a frustrating season which was capped off by Kyrie Irving leaving the Celtics. Still, Tatum took over as the leader of the team and managed to get them back to the ECF. 

Tatum is the third member of the 2017 NBA draft class to commit to a max extension. Sacramento Kings guard De'Aaron Fox agreed to a five-year, $163M guaranteed deal as well as Utah Jazz' Donovan Mitchell, who reached an agreement on a five-year max contract extension.
