UNC had the 53rd overall SOS this season, and the 136th out-of-conference SOS per Warren Nolan. The Tarheel's leading rebounders are 6-1 Ustby, 6-2 Poole who plays 21 mpg, and 6-0 Todd-Williams. They are 6-6 versus Quad 1 NET opponents and 5-6 against Quad 1 RPI opponents (South Carolina are 19-2 and 17-2 respectively).
As such, while UNC overall out-scored their opponents 73.5 ppg to 55.3 ppg (or 18.2 Scoring Margin, good for 7th best nationally), they out-scored ACC competition 67.3 ppg to 57.5 ppg (for a Scoring Margin of only 9.8 ppg). Compare to USC's scoring averages of 71.4 overall and 71.4 in SEC play, and scoring defenses of 50.2 overall and 51.2 in SEC games, for Scoring Margins of 21.2 ppg and 20.5 ppg respectively. USC had the overall #1 NET and #1 RPI nationally, while also had the overall #1 SOS and the #4 SOS out-of-conference, so those scoring margins reflect the consistency of schedule strength for them.
And while UNC was a strong rebounding team overall this season - averaging 43.03 rpg, good for 13th in the nation - and a Rebounding Margin of 7.4 rpg, good enough for 22nd nationally, they only averaged 41.7 rpg in conference games, and allowed 38.2 rpg from their conference rivals, 11th-best in the conference, for a Rebounding Margin of only 3.5 rpg. South Carolina meanwhile averaged 47.7 rpg overall and 48.9 in SEC play, while maintaining the rebound margins to 18.1 rpg overall, and 17.6 rpg in conference games. Again a consistency reflective of how consistent their schedule strength was from non-conference to conference play.
In the 18 ACC regular-season games, UNC out-scored their competition by 9.8 ppg and out-rebounded them by 3.5 rpg. In the other 13 games, they out-scored their competition by 29.7 ppg and out-rebounded them by 12.7 rpg.....
