Jayson Tatum is the undisputed franchise cornerstone for the Boston Celtics, the type of flexible, scalable star who makes assembling a championship-caliber squad a breeze. Of course, he has yet to win the Larry O’Brien Trophy in his career, but he seems to have a stronger shot than ever this season after Boston’s roster was renovated during the summer with the additions of Kristaps Porzingis and Jrue Holiday.

There’s little doubt that the Celtics’ starting five—Tatum, Jaylen Brown, Porzingis, Holiday, Derrick White, and Al Horford—are the best in the league. They’ve played like it so far, too, with not only the greatest record in basketball (28-7) but also a +10.8 net rating that outperforms every other club in the league.

Nonetheless, there is a widespread belief that the club with the better overall player will win a playoff series. Is Tatum, a top-10 player in the world, good enough to lead the Celtics to a championship over the likes of Joel Embiid of the Philadelphia 76ers, Giannis Antetokounmpo of the Milwaukee Bucks, and Nikola Jokic of the Denver Nuggets?

Only time will tell, but Tatum appears more secure than ever in his own league ranking. After Saturday’s win over the Indiana Pacers, Tatum was asked if he’d reached a “elite level of consistency as a star,” and he responded affirmatively.

“I believe so. “First team All-NBA two years in a row, so that’s kinda consistent,” he said, according to The Athletic’s Jared Weiss.

Tatum will almost certainly miss out on MVP this season, as well as First Team All-NBA honors. None of that matters if Boston wins the championship, with Tatum establishing once and for all that he is the best player on a championship team.
