NBA 2018-19: 5 sophomores poised to have a breakout season

#5 Jayson Tatum

Jayson Tatum posterized LeBron last year during the Eastern Conference Finals.

Even though he finished behind Ben Simmons & Donovan Mitchell in the race for the 'Rookie of the Year' last season, Tatum let the league know that he is not afraid to take charge when the clock's ticking and the season is on the line.

He unveiled nerves of titanium all throughout the regular season when his team was down double-digits, making clutch plays and maintaining a composure unseen in kids his age. Celtics' successful postseason run even without Irving & Hayward couldn't have been possible without this man's heroics.

He started all the 19 postseason games for the Celtics and averaged 18.5 points, giving LeBron a genuine scare in the East Conference Finals clash, falling one game short of the Finals.

The past summer saw him receiving post up coaching lessons from the Mamba, his childhood inspiration and the reason behind Jason aspiring to play in the NBA.

Tatum's cool, calm and collected in high-pressure encounters, and that's a trait which screams of a long and successful NBA career.
