Last week was the debut of the bracket projections here at Sports on Earth. A lot has happened in the seven days since. What we're seeing is a real chasm of separation, even more than before is a depth through the No. 4 line that really is separating from the rest of the pack. Up top? It's something a mixed bag. Wichita State as No. 1 vs. Michigan State as a No. 4. Or Syracuse as a No. 1 vs. Iowa State as a No. 3. Who are you taking in those games? When we have interchangeable parts like this at the top, it makes the bracket a lot more fun.

Next time we update the field, it'll be March. March! Amazing. While last week was big in terms of getting closer to cementing seeding (at this point, anyone ranked fifth or higher can lose the rest of their games and still earn a bid), the next seven days give us some more room for squeeze, but it won't be nearly as hectic.

I want to note: I do my best to abide by the NCAA's bracketing procedures and rules -- some of which are new/more lenient to the process this season. If the bracket is not quite perfect, forgive me. (The Big 12's round-robin schedule and getting seven teams into the field is making this extra tough.) We'll scrub again and re-seed next week, soon enough. Now, the power four from each region:

EAST: Syracuse, Villanova, Iowa State, Cincinnati. Composite record: 95-14.

SOUTH: Florida, Wisconsin, Creighton, Saint Louis. Composite record: 97-13.

MIDWEST: Wichita State, Kansas, Virginia, Michigan State. Composite record: 97-17.

WEST: Arizona, San Diego State, Duke, Louisville. Composite record: 95-15.

Who took the biggest hit this week of any team that's still in the field? Either Michigan State dropping from it's No. 2 seed spot, or Pittsburgh's tumble. Best advancement? Hard to argue against Wisconsin's run to the 2 line.

Leagues with multiple bids:

  • Big 12 (7)
  • Pac-12 (7)
  • Big Ten (6)
  • ACC (6)
  • AAC (5)
  • Atlantic-10 (5)
  • Big East (5)
  • SEC (2)
  • Mountain West (2)

I'll also note that Southern, who is going to run away with the SWAC league crown, is currently ineligible for the 2014 NCAA tournament. The school is appealing to the NCAA to get this reversed. In the interest of the exercise, I'm keeping Southern in -- for now.
