Since going to 7 playoff teams, the opening round is mostly blowouts.
I wondered if this year was an anomaly so I checked:
2024-25: 4/5 games won by 12+ points
2023-24: 5/6 games won by 14+ points
2022-23: 2/6 games won by 16+ points
2021-22: 4/6 games won by 16+ points
2022-23 was the only year with a lot of close games.
