Bracketology is back on ESPN.com for its 30th season. From now until Selection Sunday on March 17, we'll keep you up to date on the postseason chances and projection of your favorite teams. Our brackets update Tuesday during the non-conference schedule before shifting to semi-weekly -- Tuesday and Friday -- once conference play hits in earnest in January. We culminate with daily updates throughout Championship Week in March, all with an eye toward the 2024 NCAA men's basketball tournament.
