Best bets for Saturday, Feb. 21

The Michigan Wolverines took over the top spot in the men's college basketball rankings, and they passed their first test with a 91-80 victory against No. 7 Purdue on Tuesday. Now, the Wolverines face No. 3 Duke in the Edward Jones Capital Showcase in Washington, D.C. Michigan (25-1) has been rolling since a loss to Wisconsin, winning 11 in a row, 10 by double digits. Duke (24-2) has won 13 of its past 14, the lone blemish a three-point road setback to arch-rival North Carolina. The Blue Devils beat Syracuse by 38 points on Monday, but the Wolverines are 2.5-point favorites in the Michigan vs. Duke odds. The SportsLine Projection Model has the Blue Devils winning 60% of the time as +125 money-line underdogs and covering 67% of the time, both good for 'B' grades.

In the other top-five matchup Saturday, the Houston Cougars host the Arizona Wildcats, who lost the top ranking and dropped to No. 4 after losing twice last week. A 75-68 victory against No. 23 BYU on Wednesday helped alleviate some concerns for the Wildcats (24-2), but playing at Houston is a different ball game. The Cougars (23-3) are coming off a tough 70-67 loss at No. 6 Iowa State on Monday but are 13-0 at home. They are 4.5-point favorites in the Arizona vs. Houston odds, and the SportsLine Model has the Cougars winning in nearly 80% of its simulations. Iowa State visits BYU in another ranked matchup Saturday, with the Cyclones listed as 3.5-point road favorites. The Cougars are winning in 48% of simulations, earning a 'B' grade from the model on BYU +144 on the money line.
