Baylor was unranked in the preseason but is now 6-0 with victories over the schools that were No. 5 (Oregon), No. 12 (Michigan State) and No. 13 (Louisville) in the preseason AP poll. No other team in the country has wins like that already.

The Bears are 12th in offensive efficiency.

They're 23rd in defensive efficiency.

They're playing together, hard and well -- all of which, as I noted Friday, should solidify Scott Drew's reputation as one of college basketball's consistently good coaches. He doesn't have any top-50 national recruits on his roster. But you wouldn't know that by watching the Bears.

Baylor is No. 11 in the updated CBS Sports Top 25 (and one), which sees some shakeup in the bottom half after Arizona's loss to Butler Friday night.

The complete Top 25 (and one) is below.
