Siakam shot 13 of 23. Obi Toppin added 20 points off the bench with four 3-pointers, Andrew Nembhard had 18 points and nine assists, and Ivica Zubac scored 16 points with a double-double on the glass. Indiana won the fourth quarter 37-28.
Dejounte Murray led New Orleans with 23 points and seven assists. Williamson scored 22 on 7-of-16 shooting, and Yves Missi had 13 points, 14 rebounds and three blocks. Derik Queen added 10 points and 10 rebounds off the bench.
Haliburton finished at minus-4, the only Indiana starter with a negative plus-minus. Indiana is 1-0 and leads the season series with New Orleans. The thing to track over the next few weeks is his workload. He played 34 minutes in his first game back and carried the offense late, and how Indiana manages those minutes early in the season will shape how much of that closing role he keeps.
