Run of the mill was in regards to his X's and O's. When you hear great X's and O's coaches, you rarely hear Williams' name mentioned. Do some research. The coaches with the best players usually win. I'd take Izzo, K, Knight and a number of others over Williams any day especially with similar talent.
Check how many titles he had at Kansas. He was more likely to lose in the 2nd round than anything. Why? Because he didn't have the talent there like he had at UNC and couldn't rely on his coaching to get his team over the hump.
