Celtics news: Jayson Tatum looks back on surreal feeling after dunking on LeBron James

For everything that he has impressively done and all his amazing firsts, the most memorable moment that Celtics forward Jayson Tatum will fondly cherish is when he hammered a dunk on LeBron James.

The third overall pick of the 2017 NBA draft, Boston Celtics forward Jayson Tatum is coming off one of the best rookie performances in the postseason. The unfortunate injuries to Kyrie Irving and Gordon Hayward were a blessing in disguise for Tatum, giving him the minutes he needed to showcase his NBA-ready performance.

For everything that he has impressively done and all his amazing firsts, the most memorable moment that Tatum will fondly cherish is when he hammered a dunk on LeBron James.

According to Adam London of the New England Sports Network, Tatum was not really sure what came over him during that time.

“I don’t know why I yelled and bumped him… But I’m glad I did. I will always remember that. But I was running back on defense like, ‘Oh, my God.’ I couldn’t believe what I just did.”

Among everything he has accomplished last season, the greatest feather on his hat by far would be posterizing arguably the greatest player of all time. Not a knock on Tatum's talent, but if this is a sign of things to come, his ability to do insane things bode an awesome future for this budding star.

He averaged 13.9 points, 5.0 rebounds, 1.6 assists, and 1.0 steal per game while shooting at a 43-percent clip from the three-point line last season. Surprising us even more, he took it to another notch in the postseason, averaging 18.5 points, 4.4 rebounds, 2.7 assists, and 1.2 steals per game.

His playoff showing anchored the Celtics to face the mighty LeBron James-led Cleveland Cavaliers in the Eastern Conference Finals. Sadly, James was just too much for a resilient Celtics team as they fell short in Game 7.
