NBA stars have been showing up to various basketball run-ins this summer. Recently, Boston Celtics forward Jayson Tatum took his talents to the Rumph Classic in Philadelphia and gave everyone a teaser on what he will do this upcoming season.

J.T. is looking like he's ready to finally break out into stardom. Tatum is looking to have a redemption campaign this upcoming 2019-20 season after falling short of expectations last spring.

Many expected Tatum to have a quantum leap in his second year in the league after having a magnificent rookie season in 2017-18. The former third overall pick earned a spot on the 2018 All-Rookie First Team by posting averages of 13.9 points, 5.0 rebounds while shooting at an efficient 47.5 percent from the field and 43.4 percent from three.

Moreover, Tatum helped the Celtics take LeBron James and the Cleveland Cavaliers to the limit in the 2018 Eastern Conference Finals despite having Kyrie Irving and Gordon Hayward on the sidelines. The Celtics ultimately fell to The King in seven, but the then-19-year old went mano-y-mano with the best player in the world, scoring 24 points on 9-of-17 shooting in Game 7, seemingly cementing his status as a future superstar in the NBA.

However, Tatum didn't have the jump many analysts raved about prior to the start of the 2018-19 season. Tatum didn't have a defined role with the team and struggled to find his season-long rhythm with Hayward and Irving returning to the lineup. While his production increased to 15.7 points and 6.0 rebounds in year two, his efficiency dropped to 45.0 percent field goal shooting and 37.3 percent 3-point shooting.

With Irving no longer hogging the spotlight, Tatum has the opportunity to unleash himself this season.
