College basketball Power Rankings: Michigan State back on top, but for how long?

So, uh, last week happened.

It's often said, most notably by Mike McDermott in "Rounders," to always leave yourself outs. While the weekly Power Rankings might not be considered high-stakes gambling, hedging predictions is always a sound strategy. In other words, don't make Kentucky No. 1 and then write: "The Wildcats don't have any true tests on their schedule until late December ... get used to Calipari's Cats at No. 1."

Because when that same Kentucky team loses to Evansville at home about 36 hours after the rankings come out, suddenly the Power Rankings look ... not great.

Lesson learned.

We forge on, however, and Kentucky's loss leaves a bigger question: Who's No. 1 right now? Duke will get that honor in the polls because the Blue Devils were No. 2 and that's just how polls operate. But we had Michigan State in the No. 2 spot last week, and all the Spartans have done since then is go to New Jersey and knock off Seton Hall despite a performance for the ages from Myles Powell.

Coming out of the Champions Classic, I thought Michigan State looked like a better team than Duke, and thus ranked the two teams that way. The early weeks of the Power Rankings are more qualitative than résumé-based, so the fact that the Spartans have a loss and Duke doesn't isn't the end of the world. And if we don't want to go quantitative, Michigan State is still No. 1 in the BPI and at KenPom.

Fortunately, this debate might be settled on the court. If Michigan State gets through the Maui Invitational unscathed -- given Kansas is on the other side of the bracket, that's not a sure thing -- and Duke handles the 2K Classic and a couple of home games, these two teams will face off on Dec. 4 in East Lansing.

1. Michigan State Spartans (2-1)
Previous ranking: 2
This week: vs. Charleston Southern (Monday)

If Malik Hall can produce like he did against Seton Hall, Tom Izzo will have a new dimension on the offensive end. Hall is capable of stepping out and making shots from the perimeter -- he was 3-for-3 from 3 against the Pirates -- which opens up the Spartans' offense and gives more space to Xavier Tillman and Cassius Winston. Thomas Kithier doesn't have that ability on a consistent basis, and it hasn't quite clicked for Marcus Bingham yet. But if Hall suddenly becomes a factor in the frontcourt, Michigan State can score from all five spots when he's on the floor.

2. Duke Blue Devils (4-0)
Previous ranking: 3
This week: vs. California in New York, vs. Georgetown/Texas in New York (Friday)

There were questions in the preseason about whether Tre Jones could become a true go-to-guy for the Blue Devils this season. Those questions aren't quite as prevalent two weeks into the season. He took over the game late for Duke against Kansas in the opener, then went out and scored 31 points and dished out six assists against Georgia State last Friday. The Duke freshmen are taking more time than last year's group did in terms of adapting to the college game, so Jones has had to pick up the slack -- and it's working so far. Oh, and he's still the same menace he was last year on the defensive end.

3. Louisville Cardinals (4-0)
Previous ranking: 4
This week: vs. USC Upstate (Wednesday), vs. Akron (Sunday)

Chris Mack needed to find answers at the point guard spot entering the season, especially once freshman David Johnson went down with an injury. So far, it's been smooth sailing. Darius Perry was terrific against Youngstown State, dishing out 12 assists to just one turnover -- and then Saint Joseph's graduate transfer Lamarr Kimble stepped up against Indiana State when Perry was struggling. Kimble had 13 points, four rebounds and three assists against the Sycamores. On Sunday against NC Central, it was a little bit of both: Perry and Kimble combined for 19 points and 12 assists in another easy win.

4. Oregon Ducks (4-0)
Previous ranking: 5
This week: vs. Houston (Friday)

There are only a handful of teams in the country that can mix and match his lineups the way Dana Altman does with his roster. He's so spoiled for choice that five-star freshman C.J. Walker played only five minutes in the Ducks' win over Memphis. Altman has leaned on experience early on, with graduate transfers Shakur Juiston and Anthony Mathis doing the heavy lifting alongside senior guard Payton Pritchard. Will Richardson was a bright spot against Memphis; after junior college transfer Chris Duarte went out with an injury, Richardson came in and played 31 minutes, scoring 10 points and dishing out six assists. Friday's game against Houston is quietly one of the best games of the week.

5. North Carolina Tar Heels (3-0)
Previous ranking: 6
This week: vs. Elon (Wednesday)

There might not be a team more banged up than the Tar Heels right now. Expected starter Brandon Robinson is sidelined with a sprained ankle he suffered early in the preseason, and Sterling Manley has been out with knee soreness. Freshman guards Anthony Harris and Jeremiah Francis have been out with injuries from high school. Roy Williams has had to rely heavily on Cole Anthony thus far, and the freshman has obliged. But at some point, the Tar Heels are going to need more consistency from the supporting cast -- and health from the rest of the roster.

6. Kansas Jayhawks (2-1)
Previous ranking: 7
This week: vs. East Tennessee State (Tuesday)

Bill Self is still clearly tweaking his lineups to find the best combination. After playing just 14 combined minutes against Duke and UNC Greensboro, Silvio De Sousa logged 23 minutes and started against Monmouth. David McCormack started against Duke and UNC Greensboro but came off the bench against Monmouth -- and had 17 points and 11 rebounds. Don't sleep on this week's game against East Tennessee State. Steve Forbes' team has won 100 games the past four years and is favored to win the Southern Conference title this season.

7. Gonzaga Bulldogs (4-0)
Previous ranking: 8
This week: vs. UT Arlington (Tuesday), vs. Bakersfield (Saturday)

Entering the preseason, it looked like Gonzaga could be one of the deepest teams in the country, with 10-plus guys able to contribute. With Killian Tillie injured, Oumar Ballo declared an academic redshirt and freshmen Martynas Arlauskas and Pavel Zakharov not contributing much early, Mark Few has been relying on a seven-man rotation through the first couple of weeks. The star of the group so far has been Filip Petrusev, who showed flashes of his ability last season but is doing it consistently through four games. He tallied two double-doubles and is averaging 18.3 points and 9.3 rebounds.

8. Ohio State Buckeyes (3-0)
Previous ranking: 12
This week: vs. Stetson (Monday), vs Fort Wayne (Friday)

Home wins over Cincinnati and Villanova -- the latter a 25-point throttling -- will hold up well throughout the season and give the Buckeyes momentum heading into a December stretch that includes games against North Carolina, Kentucky and West Virginia, as well as the start of Big Ten play. Chris Holtmann has gotten stellar point guard play from the newcomer duo of Florida State transfer C.J. Walker and freshman D.J. Carton. Walker is averaging 8.3 points and has 10 assists to just two turnovers in his past two games, and Carton is coming off the bench but putting up 11 points and 3.7 assists.
