Welcome to the second edition of one of the most popular Bracketology features here at ESPN Insider. Bracket Math provides an up-to-the-minute assessment of the entire Division I men's basketball landscape. You'll know who we'd put in the bracket -- and why -- at any given point of the season.

Bracket Math will appear multiple times each week. And of course, you can find it here daily (and even more frequently) during the frenzy that is Championship Week.

We know you want bracket updates as often as possible. When that's not practical, Bracket Math will always tell you where your team stands in the NCAA tournament selection process.

This edition of Bracket Math includes games through Feb. 2. Rankings reflect an up-to-date S-curve from yours truly, posing as one hypothetical member of the NCAA men's basketball committee.

Notes on the 'new' math

• Obviously the big question in college basketball for the next 24 hours will be "Who's No. 1?" While I expect Indiana to top the major polls on Monday, the fact is that Florida -- up to this point, at least -- has played a bit more consistently against slightly better competition (again, for now).

• Most impactful Saturday wins: Pitt (over Syracuse), Saint Louis (Dayton), Air Force (San Diego State), Miami (at NC State), Kentucky (at Texas A&M), Kansas State (at Oklahoma), Florida (Ole Miss), Iowa State (Baylor), Boise State (UNLV), Indiana (Michigan).

• Most damaging losses: Florida State (versus Duke), UMass (at Charlotte), Colorado (at Utah), St. John's (at Georgetown), Kansas (Oklahoma State), Ohio (at Akron), Wyoming (at Colorado State), Indiana State (at Drake in OT).

The Bracket

This is where I believe teams would fall if Selection Sunday were today. Remember, the S-Curve flows left to right, then right to left, then back again as you read down the chart. It gives you a look at which teams are locks, which teams still have work to do, which teams are primed to land automatic bids, and which teams are on the right and wrong side of the bubble. (Note: Teams in ALL CAPS are current conference leaders.)
