One of the best things about writing for DBR is that the readers are knowledgeable enough to let you know when you screw up.

My article, posted Monday, asserted that Coach K was 13-9 against Roy Williams at UNC – 6-4 in Durham; 6-4 in Chapel Hill and 1-1 in Greensboro.

As several readers pointed out – that’s incorrect. I miscounted.

Coach K is actually 12-9 against Roy at UNC (he’s also 3-1 against Roy at Kansas). That breaks down to 5-5 in Cameron, 6-4 in the Smith Center and 1-1 in Greensboro (the 2011 ACC Tournament finals).

Re-checking the numbers, I was struck by a couple of trends. One is the fact that I’ve noted before is that both teams have better road records in the series than home records. The other was a note that Barry Jacobs has made – that Duke has a much better record in the first meeting of the season (8-2), while UNC has been better in the second meeting (7-3).

Interesting that Duke’s only wins in the regular season finale have coming in the three years when Duke swept the Heels (2004, 2010 and 2013). UNC’s only wins in the first matchup of the season came in their two sweeps (2007, 2009).

The real interesting number is when two trends come together – Duke’s relative road success and its success in the first matchup – when the first matchup is in Chapel Hill, Duke always wins. At least always in this century. UNC last won a midseason matchup in Chapel Hill in 1998 (the famous “Rumble in the Jungle”). Since then, Duke has won seven straight midseason games in Chapel Hill (2000, 2002, 2004, 2006, 2008, 2010, 2012).

That will be something to watch next season, when the two teams should open the season series in Chapel Hill (unless ACC expansion messes that up).

Anyway, I think I’m right about that. But if I missed on any of my numbers, I hope my DBR readers will correct me. I apologize for my mistake Monday.
