Big Ten conference Men's College Basketball power index on ESPN. The BPI is the best predictor of a team's performance for the season.

Arkansas basketball head coach John Calipari had thoughts on the changing state of the college basketball landscape.

In the Big Ten, one of the stories of the college basketball season is brewing. Nebraska improved to 11-0 for the first time in program history after recording an 83-80 upset win over No. 13 Illinois. Nebraska guard Jamarques Lawrence knocked down a 3-pointer with 0.2 seconds remaining to give No. 23 Nebraska its first ranked win of the season.

Let's take a look at who to watch for in today's Arkansas-Texas Tech matchup.

Arizona took over the top spot in the AP Top 25 men's college basketball poll on Monday, a reward for a perfect start to the season that includes a quartet of wins against ranked foes, including a lopsided victory over Auburn last weekend.

Oscar Cluff has 20 points and 10 rebounds, and has made all nine of his shots. In five second-half minutes, he has 13 points and four rebounds. Remarkable dominance against Marquette, and he convinced Painter to challenge the out of bounds call and won.

The Iowa State Cyclones continue to move up in the power rankings with an undefeated record.

The big tweaks will come in the teens this week with No. 12 Alabama, No. 13 Illinois, No. 16 Texas Tech and No. 18 Florida all sustaining losses. No. 23 Nebraska's win over No. 13 Illinois and No. 25 UCLA's loss to No. 8 Gonzaga should also be a factor in the final tabulations.
