This high-scoring affair left NBA fans in awe, as both teams showcased their offensive firepower, setting a new standard for scoring in a regular-season game. The over/under line for this game was set at an astonishing 252.5 points, the highest in over two decades. The total points scored surpassed all expectations, eclipsing the line and ultimately reaching an extraordinary 309 points.

Going into the game, Indiana's scoring trends hinted at the prospect of a high-scoring encounter. The Pacers had already witnessed the over hitting in 11 of their 12 previous games, consistently exceeding the projected line by an average of nearly 14 points. Tuesday's clash against the Hawks proved to be no exception, adding to their reputation as a team capable of producing offensive fireworks.

Both teams showcased their offensive prowess throughout the game, with seven Pacers players reaching double figures in scoring. Rookie Tyrese Haliburton led the charge for Indiana with an impressive 37 points, while Trae Young led the Hawks with a stellar performance of 38 points.

The shooting accuracy from both squads was remarkable, as they each shot an impressive 60% from the field and 48% from beyond the arc. In fact, Indiana's 22 made three-pointers stood as the second-highest tally in a single game this season, narrowly missing the record set by the Dallas Mavericks earlier in the season.

While the offensive display stole the headlines, it is crucial not to overlook the resilience of the Pacers, who staged a remarkable comeback after trailing by a significant margin. Their victory not only secured bragging rights but also cemented their place in the knockout round of the Eastern Conference's Group A in the In-Season Tournament, boasting a flawless 3-0 record.

The highest-scoring game in NBA history took place in 1983, when the Detroit Pistons defeated the Denver Nuggets in a thrilling triple-overtime affair, accumulating a staggering total of 370 points. Meanwhile, the record for the highest non-overtime scoring game rests with a 1990 clash between the Golden State Warriors and the Denver Nuggets, wherein the teams combined for 320 points.
