Bulpett added that while the Celtics and San Antonio Spurs have had contact regarding a potential trade for Kawhi Leonard, the C's are seemingly unwilling to move Tatum or Brown, and it is unclear if they would even part with the Sacramento Kings' 2019 first-round pick.
While Leonard is an All-Star when healthy, he appeared in just nine games last season due to a quad injury.
Meanwhile, Brown and Tatum helped lead the Celtics to within one game of reaching the NBA Finals despite the fact that forward Gordon Hayward and guard Kyrie Irving were out due to injury.
The 21-year-old Brown improved greatly from his rookie season in 2016-17, as he averaged 14.5 points and 4.9 rebounds per game during his second campaign. Brown raised his level of play during the playoffs with 18.0 points and 4.8 rebounds per contest.
The Celtics showed a great deal of confidence in Tatum last year by trading out of the No. 1 overall spot in the 2017 NBA draft and selecting the Duke forward at No. 3.
That move paid immediate dividends, as Tatum averaged 13.9 points and 5.0 rebounds per game while shooting 47.5 percent from the field and 43.4 percent from three-point range en route to being named a Rookie of the Year finalist.
Like Brown, Tatum also improved in the playoffs, averaging 18.5 points, 4.4 rebounds and 2.7 assists per game.
Brown and Tatum are two of the NBA's best young wing players, and they are each talented enough to develop into perennial All-Stars.
It can be argued that Leonard gives Boston a better chance to win a championship in 2018-19 if healthy, but a core of Irving, Hayward, Brown, Tatum, Al Horford and Terry Rozier has dynasty potential.
Provided he opts out of his contract after this season, Leonard will likely require a max contract extension, whereas Boston has some time before it has to worry about that with Brown and Tatum.
There is pressure to win now in Boston, but with players like Brown and Tatum improving rapidly, the Celtics likely already have a team capable of winning a title.
