Ok, I found the article from 2019 talking about it. Since 2004, every national champion has ranked at least 12th in the week 6 AP poll, and at the time, the eventual national champ had an avg ranking of 6.1 in week 6. Baylor was 2 and Kansas was 7, so not sure what the updated stats would be. So basically, no need to watch from week 6 until the tourney starts
