The Boston Celtics have been the turnaround story of the NBA season thus far. One change from Jayson Tatum is being credited as a big reason why.

Talent has never been a question for Jayson Tatum. During his best moments in his early years, future MVP was a realistic ceiling for what he could achieve, given his advanced skill mixed with his supreme size at such a young age.

But the JT hype train slowed down a bit in recent seasons as critics started questioning the Celtics star: Does he make his teammates better? Is he capable of being the top dog on a contending team?

While the answers to those questions are far from answered, Jayson Tatum has skewed much closer to the affirmative based on what he's shown this season.

Via Jake Fischer of Bleacher Report:

League figures credit Tatum—known for his quiet, humble demeanor—for taking a larger role as a vocal leader for Boston this season. For a coaching staff with such deep San Antonio ties, Tatum’s approach to his craft, his professionalism, his consistency all runs parallel to those of Kawhi Leonard and Tim Duncan.

Leading by example still matters, too. During games, both Tatum and Brown’s commitment to defense has helped establish expectations down Boston’s roster.

Boston's turnaround has been the result of a number of factors and players stepping up. But more than likely, they're only going as far as Jayson Tatum can carry them.
