Selection Sunday is just over four weeks away, and Saturday's slate in college basketball could go a long way toward determining how the bracket shakes out. The day is headlined by one of the biggest regular-season college basketball games in recent memory with No.

First place in the Big 12 is up for grabs when No. 6 Houston (20-4, 12-1) takes to the court Saturday in Tucson against No. 13 Arizona (17-7, 11-2). The Cougars and the Wildcats will each take the court looking to extend 3-game winning streaks.
