Kansas vs. Baylor is the centerpiece of Saturday's college basketball schedule because it's a showdown featuring two top-five teams -- one of which (Baylor) is on a historically great 23-game winning streak. But Gonzaga vs. BYU is also excellent and worthy of attention.

The Zags won again Thursday night.

So did the Cougars.

As a result, those two teams will enter Saturday's matchup having combined to win 26 consecutive games. Gonzaga is 27-1 overall, 13-0 in the West Coast Conference and on a 19-game winning streak after Thursday night's 71-54 victory over San Francisco. And though BYU's record (22-7, 11-3) is not as impressive as Gonzaga's even after Thursday night's 85-75 victory over Santa Clara, it should be noted that the Cougars are actually 14-2 this season when their best player, Yoeli Childs, is in the lineup.

He'll be in the lineup Saturday.

So this really should be a great game.

Gonzaga is No. 1 in Friday morning's updated CBS Sports Top 25 And 1 daily college basketball rankings for the 54th consecutive day. BYU is No. 22. Tipoff for Saturday's game inside the Marriott Center is scheduled for 10 p.m. ET.
