The Boston Celtics showcased their revamped lineup and newfound team chemistry in a resounding victory over the Indiana Pacers on Wednesday night. This standout performance further solidified the Celtics' new mentality of sacrifice and buy-in from their star-studded roster.

With the addition of Kristaps Porzingis and Jrue Holiday, the Celtics' starting five has become a nightmare for opposing teams to defend. Alongside the rapidly improving Derrick White, the Celtics now boast four players capable of consistently scoring 20 or more points a game. However, this abundance of scoring options raised concerns about shot distribution and decision-making in the team's first two wins of the season.

Nevertheless, those concerns quickly faded as the Celtics achieved back-to-back historic blowouts against the Washington Wizards and now the Indiana Pacers. The key to their success lies in the team's elevated level of buy-in and sacrifice. Each player within the potent scoring group has embraced their specific roles, leading to a dominant 155-104 victory over the Pacers.

In their latest game, it was Kristaps Porzingis who willingly took a backseat, attempting just two shots in the first 18 minutes. Instead, Porzingis focused on playing stellar defense, setting screens, and making crucial passes. Head coach Joe Mazzulla commended Porzingis for his humility and team-first approach, emphasizing the importance of managing each other and having open conversations.

The Celtics' recent blowout wins have showcased their new mentality and unselfishness. Against the Wizards, Jaylen Brown's hot shooting prompted Jrue Holiday and Derrick White to defer to him, actively seeking ways to get him clean looks. While there have been moments in earlier games where the team forced the ball into trouble, the overall commitment to executing team actions and generating high-quality shots has grown. The addition of Jrue Holiday, with his own understanding of offensive flow and defensive pressure, has further bolstered this collective mindset.

Holiday noted that the team's offensive success goes hand-in-hand with their defensive intensity, as numerous stops and pressure on opponents facilitate easy scoring opportunities in transition and one-on-one situations.

The Celtics understand that facing soft defenses like the Wizards and Pacers every night is unlikely, but their mentality of sacrifice has already yielded positive results. Each player has had their chance to shine, and the consistent mindset of the team has enabled Boston to control games from start to finish.

Looking ahead, the Celtics will now take their newfound mentality and chemistry on the road, with three consecutive away games starting Saturday night in Brooklyn. The team aims to maintain their high level of competitiveness and mental toughness throughout these challenging matchups.

Coach Mazzulla acknowledged that maintaining mental toughness is crucial in the NBA, where games can quickly change dynamics. The Celtics' ability to respond to runs and maintain consistency throughout the entire game was a testament to their maturity and mental fortitude.

As the Celtics embark on their road trip, they hope to carry forward the positive momentum gained from their dominant win over the Pacers. Building upon their new mentality and team chemistry, the Celtics strive to establish themselves as a force to be reckoned with in the league.
