March Madness recap for those who know nothing about March Madness

The first two rounds are over, along with the upset watches, the Cinderella teams, and the four days of endless basketball. Now the campaign for the championship kicks into high gear. This is what's known as the "Sweet Sixteen," as in there are 16 teams left to duke it out (not included Duke, because they're out). UCLA coach Ben Howland said it best: There are no more upsets after the first two rounds. Any team can beat anyone else at this point. With that said, there are a few rules to know about the March Madness end-game.

1. Double-digit seeds lose. The first few rounds are where underdogs feast on overrated teams from bigger conferences. But in the Sweet Sixteen, the weak, upper-seeded teams fade and the big boys come out to play. So while watching (12th seed) Western Kentucky and (12) Villanova buck the odds has been fun, don't bet on them this weekend. The exception to this rule may be (10) Davidson vs. (3) Wisconsin. Davidson has the player of the tournament (so far) in Stephen Curry and a solid point guard in Jason Richards. They will be no pushovers in their game against the Badgers.

2. All four number one seeds never make it to the final four. Despite how easy it is to imagine the top seeds all advancing, history has shown that one or two top teams will fall. Look for Memphis to be that team this year. Memphis played a weak conference schedule and few close games, which hid their free-throw shooting woes. Against Mississippi State they nearly blew their lead by shooting 46 percent from the line (a good team should shoot at least 70). Now the Tigers face a tough Michigan State team in the round of 16, and possibly (2) Texas in the Elite Eight – the winners from the Sweet Sixteen, if you're following along.

3. While all four top seeds never make it to the final four, at least two always do. Expect that those two to be UCLA and Kansas. Both face weaker, double digit seeds in the Sweet Sixteen and both two seeds have been cleared out of their way (Duke and Georgetown, respectively). North Carolina has the toughest road of the top-ranked seeds. They have to go against a scrappy (4) Washington State, and then against either (2) Tennessee or (3) Louisville. Both are capable of beating the Tar Heels.

The closest match up and game-to-watch this weekend could be the Texas Longhorns vs. (3) Stanford Cardinals. Neither team has an answer for how the other scores. Texas uses the quickness of their ball handlers D.J. Augustin and A.J. Abrams to create points, while Stanford's guards are far slower and should be no match. But the Cardinals counter with twin 7-footers in Brook and Robin Lopez to score and rebound near the basket. The Longhorns are shorter, and the Lopez brothers should have a field day.

These are your basic rules to follow for the next four days, but beyond them, madness reigns. So kick up your feet for the next four days of college hoops, as the table is set for the 2008 champion.
