Jayson Tatum Over 15.5 rebounds + assists ⭐⭐⭐⭐

The discussion before Game 1 of the NBA Finals has centered on Tatum’s ranking among the top players in the league. Is he number four? Is he number nine? Ultimately, it doesn’t matter, as the Celtics are just four victories away from becoming the top team in the NBA, with Tatum playing a significant role in their success.

Tatum has been dominating in the paint, using his size and strength to control the boards with an average of 10.4 rebounds per game in the playoffs. He has hit double digits in 11 out of 14 games and has also displayed his ability to make plays, capitalizing on the talent of his teammates.

Tatum is currently averaging 5.9 assists per game and has achieved at least five assists in 11 games. He has recorded over 15.5 combined assists in 10 games, with six of them occurring in his last seven games. Based on our odds converter, these statistics suggest a 51.22% chance of winning, with a $10 bet resulting in a payout of $19.52.

Jayson Tatum Over 26.5 points ⭐⭐⭐⭐

There is some debate surrounding Tatum’s performance, with some questioning if certain “analysts” are actually watching the games. Have they overlooked his quieter games in the first round against the Miami Heat, leading them to doubt his ability to score in the playoffs?

While Tatum doesn’t have to score a lot for Boston to win, he has shown steady improvement throughout each series. In the Eastern Conference Finals, he averaged 30.3 points per game and scored at least 27 in four of his last seven games. Against the Mavericks, particularly in Game 1 against a talented Doncic, Boston will probably lean more on Tatum for scoring, especially in the paint.

This season, the Mavericks allowed an average of 29.8 2-pointers per game, ranking them 10th in the league. They also gave up the ninth-most points to power forwards, with an average of 24.58 points allowed. With these statistics, the odds suggest a 53.49% chance of winning, and a $10 bet could result in an $8.70 profit.

Jayson Tatum Under 2.5 made 3-pointers ⭐⭐⭐

While I can give Tatum plenty of credit for guiding Boston to a 12-2 playoff record, his three-point shooting has been less than stellar, resembling how I think Donnie Wahlberg would shoot if asked to fill in for the team.

Tatum has primarily been scoring inside the paint, shooting below 31% from three-point range in every series of the postseason. Overall, he is shooting just 29% from beyond the arc. Despite his struggles from deep, the Celtics have not relied on his three-point shooting, as Derrick White currently leads the team with an average of 3.4 threes made per game.

When Kristaps Porzingis returns, it will likely reduce Tatum’s three-point shooting burden. Tatum usually makes an average of 2.1 three-pointers per game and has fallen short of 2.5 in 11 out of 14 games. I believe there is great value in these odds, even though they suggest only a 48.54% chance of winning. A $10 bet could potentially pay out $20.60.
