Dallas Spoiled Haliburton's Home Return. Now Everybody's Watching Flagg's Shoulder.

Indiana welcomed Tyrese Haliburton back to its home floor, and Dallas turned the celebration into a first-half beatdown. The Mavericks scored 44 in the first quarter and 33 in the second. Indiana scored 27 and then 16. That's 77–43 at halftime. The Pacers didn't lose because of one late mistake; they spent half the game getting cooked.

Dallas won 121–105 on October 23 behind Kyrie Irving's 24 points. Irving hit five of ten threes, and P.J. Washington added 20 points, 13 rebounds and three blocks. Max Christie scored 16, Naji Marshall had 15 and six assists, and the Mavericks got contributions from across the rotation. That matters because the night didn't go according to plan for Cooper Flagg.

Flagg left after injuring his left shoulder on a hard foul during a breakaway dunk attempt. Reuters reports 14 points, five rebounds and six assists before he left late in the first half. He did not return after halftime. His availability requires a medical update, not social-media speculation.

The injury changed the conversation, but it didn't create Dallas' lead. The Mavericks had already opened the game with a 22–6 run and kept punishing Indiana's mistakes. They finished with eleven blocks, ten steals and fourteen made threes on 34 attempts. Indiana hit just seven of 32 threes and turned it over nineteen times.

Pascal Siakam scored 23 for the Pacers, Haliburton had 18 points, six rebounds and seven assists, and Andrew Nembhard added 16. Those aren't zeroes, but the Pacers never had enough consistent offense to answer Dallas' early pressure. Haliburton went 0-for-4 from three, and Indiana's second quarter was a complete offensive shutdown.

Indiana did win the third and fourth quarters, 33–21 and 29–23. I'm giving them credit for not folding completely. But here's the problem: those two periods only cut a 34-point halftime hole to sixteen. That's the difference between showing some pride and actually changing the result.

Dallas' defense deserves a bigger mention than it usually gets when people see Kyrie's scoring line. The Mavericks contested shots, created transition chances and made the Pacers uncomfortable before their half-court actions could develop. Washington's rebounding and rim protection gave the guards freedom to pressure the ball. That's a repeatable recipe if they stay disciplined.

My take: the Mavericks got a needed response after Houston beat them in the opener, but the Flagg injury is the part that could linger. A young player can score 32 one night, then get hurt in a physical game the next. You don't build a season around assuming he'll be fine just because the team won without him for a half.

For Indiana, the crowd deserved a better welcome-back performance. The Pacers can't rely on Haliburton's passing genius to erase a quarter with sixteen points. Dallas should enjoy the road win and get a clear update on Flagg before facing San Antonio. That's the responsible read: good basketball from the Mavericks, legitimate injury concern, and a rough home opener for Indiana.
