Jayson Tatum has one thing on his mind.

The Boston Celtics star entered Monday's Game 5 of the 2024 NBA Finals just one victory away from the first championship of his career. And even though he is eligible to sign the largest contract in NBA history during the upcoming offseason, the focus is reportedly all on the Larry O'Brien Trophy.

"I talked to his agent, Joe Wexler, earlier today," ESPN's Adrian Wojanrowski said ahead of Monday's contest (50-second mark). "Interestingly enough, he says he and Tatum have not discussed the elements of that deal all season. He says Tatum hasn't talked about postseason MVP awards. The only thing he's talked about is winning a championship."

Wojnarowski explained Tatum is on the precipice of landing a five-year, $315 million extension, which will be the largest in league history.

Notably, Tatum's Celtics teammate, Jaylen Brown, has the largest contract in NBA history at this point, although Wojnarowski said the former's impending deal will "eclipse" it by approximately $30 million.

Assuming Tatum takes home the title this year, there will not be much missing from his resume.

He will be a champion, four-time All-NBA selection and five-time All-Star who has been to the postseason every year of his career since the Celtics selected him with the No. 3 overall pick of the 2017 NBA draft.

Perhaps the best thing from Boston's perspective is that he is just 26 years old.

While there isn't much room for improvement given how talented he already is, that also means Tatum will likely continue performing at an All-NBA level for years to come. If that's the case, the Celtics will likely remain on the short list of championship contenders throughout the duration of the head-turning contract extension.

And that will make the price tag well worth it.
