Boston Celtics swingman Jayson Tatum took the next step to stardom this season and he is confident that he'll play even better once action resumes on June 30.

The 6-foot-8 Duke alum continued to work on his game during the unprecedented hiatus and sent out a stern reminder to the rest of the league.

Jayson Tatum, 22, had an impressive rookie season in 2017-18 after being drafted by the Celtics third overall.

Following a rather lackluster sophomore year where he failed to exceed lofty expectations, fans are once again back on the Tatum bandwagon this season. The young two-way star made it to the All-Star game for the first time last February after tallying career highs across the board.

Tatum led the Celtics in scoring, norming 23.6 points on 44.8 percent shooting from the field and 39.8 percent from downtown. He also registered 7.1 rebounds, 2.9 assists, and 1.4 steals per game in 59 appearances.

While Tatum's development was certainly hampered by Kyrie Irving's presence last season, he seems more comfortable sharing the floor with Boston's new point guard Kemba Walker.

With Tatum finally living up to the hype, the Celtics managed to hang with the juggernauts of the Eastern Conference and tallied a 43-21 record — third in the East behind the Milwaukee Bucks and Toronto Raptors.

He displayed great maturity for a player just on his third year and fully embraced being the top guy in head coach Brad Stevens' offense.

After taking flak last year for his supposed over-reliance with his perimeter game, Tatum made the proper adjustments and is doing a much better job now with his shot selection.

As good as he has been all year, it's true that Tatum is barely just scratching the surface of what he could become. Now that's indeed a scary sight for the rest of the 29 NBA teams.
