Pacers vs Celtics Game 1 Predictions & NBA Picks Today (5/21)
The Pacers head into tonight’s game as major underdogs at TD Garden. BetOnline is heavily favoring the Celtics to take a 1-0 NBA ECF series lead at -470 odds, which carry an implied win probability of 82.5%.
Nevertheless, the Pacers and Celtics are set to re-engage after colliding five times during the 2023-24 regular season. The series was back and forth but Boston had the edge in the end, winning three of the matchups. Interestingly enough, the C’s won both of the matchups at TD Garden, first notching a massive 155-104 victory back in November before defeating the Pacers 129-124 in January.
Playing in Boston has been tough on Indiana for over half a decade at this point. Since January 2019, the Pacers have dropped 10 of 11 trips to TD Garden, being outscored by an average of 12.5 points per game. In fact, they haven’t won in Beantown since December 2022.
The Pacers were also in action more recently, which could plague them. After all, they’re only. 7-10 SU (41.2%) when playing with a rest disadvantage whereas the Celtics are 26-3 SU (89.7%) when having more time off than their opponents.
How will inequal rest affect the Pacers in Game 1?
The Pacers are boasting one of the better postseason offenses, but scoring against the Celtics won’t be easy tonight. Boston surrendered a minuscule 96.7 points per game through the first two rounds, allowing its opponents to only shoot 44.9% from the floor and 33.8% from deep.
Indiana’s defense was just below average in Rounds 1 or 2, ranking fourth-worst in points, seventh-worst in field-goal percentage, and fifth-worst in three-point percentage allowed this postseason.
The Celtics simply have too many all-star options — from Jayson Tatum to Derrick White — to contain. Even with Kristaps Porzingis sidelined again with a calf injury, Boston has more than enough talent to give Indiana plenty of headaches.
To me, it’s a no-brainer to back the Celtics to win Game 1. They’ve been nearly unstoppable at TD Garden throughout the 2023-24 schedule and haven’t even broken a sweat in the playoffs. The Celtics also have had more rest than the Pacers, which could be an advantage after the latter’s grueling series with the Knicks.
With that in mind, let’s also take the Celtics to cover the 10-point spread. Again, they outscored the Pacers by nearly 13 PPG in their last 11 clashes in Boston. Additionally, Indiana is only 7-10 ATS with a rest disadvantage this year. Considering how they beat the Pacers by 50-plus points at home earlier this season, take the C’s to cover.

It’s a big number to surpass, but I’m taking the Over on Jayson Tatum’s 10.5-rebound total (+112) for the best Pacers vs. Celtics Game 1 player prop.
Tatum leads all Celtics with 10.4 rebounds per game in the playoffs and his performances have only improved as time goes on. The 26-year-old superstar is averaging a 10.8 RPG clip across his last eight games, finishing with the Over six times. He now gets to face the Pacers, who are collecting the fifth-fewest rebounds in the playoffs.
Having hit the Over in four of his last six games against the Pacers, it’s easy to see why you should sprinkle some action on this Tatum prop.
