North Carolina’s 74-63 win over Louisville late Wednesday doubled as the Tar Heels’ ninth top-50 RPI victory and provided them with a two-game cushion atop the ACC standings. In other words, Roy Williams is about to win his eighth ACC regular-season title in a 13-year span, which will be six more than Duke’s Mike Krzyzewski will have won in that same time frame.

Impressive stuff.

And let the record show the prediction here has North Carolina ultimately ending up as a No. 1 seed in the NCAA Tournament, a prediction with which our Jerry Palm agrees. That’s why I now have the Tar Heels ranked fourth in the Top 25 (and one) — because the resume is taking top-seed form. They own six wins over teams also ranked in the Top 25 (and one). They only have two sub-40 losses, both of which came before the calendar turned to 2017.

UNC’s jump to No. 4 in the Top 25 (and one) caused Baylor, Oregon and Arizona to each drop one spot, no fault of their own. And Butler’s jump from 19th to 11th after its 74-66 victory at Villanova caused West Virginia, Kentucky, Purdue, Florida, Notre Dame, Wisconsin, Cincinnati and Florida State to each drop one spot, also no fault of their own. Meantime, Oklahoma State and Wichita State are now 25th and 26th. If you’re wondering, Minnesota would be 27th. Richard Pitino’s Gophers have won six straight games and can reasonably be ranked. I hate leaving them out.
