Tatum has been considered the best player on the Celtics for a while now. Even though he didn't win the NBA Finals MVP or even the Eastern Conference Finals MVP, he is considered better than Brown. Now that he's won a championship, does he have anything more to prove? The answer is yes, and the prime example of why happened over the summer.

Tatum said he's chasing Larry Bird as the greatest Celtic ever. Why isn't Bill Russell the measuring stick? The post Jayson Tatum is entitled to his opinion on Bird being the ‘best Celtic ever’, but what about Bill Russell?

"If you aspire to chase (Bird)," Tatum said, "it comes with a level of focus and motivation every single day to be the best you can."
