​Outside of Donovan Mitchell, Jayson Tatum was the most impressive rookie from the 2017 NBA Draft class. 

Danny Ainge had the opportunity to take Tatum with the first overall pick that year, but confidently traded down to the third pick knowing that neither the 76ers nor Lakers would take a chance on the Duke product.

Joking with Kyrie Irving, Tatum took a jab at Ainge for waiting so long to draft him. 

Originally, many didn't see where Tatum fit with the ​Boston Celtics, as the team already had two elite small forwards in Jaylen Brown and ​Gordon Hayward.

As we know, Hayward would suffer a season-ending ankle injury in his first game as a Celtic, pushing Tatum into the limelight for the rest of the year. Tatum would take full advantage of this opportunity, averaging 13.9 points and 5.0 rebounds during the regular season.

Tatum must have the 76ers and Lakers having nightmares right now. The man has one heck of a future.
