The top-ranked Duke Blue Devils were the only ranked team in action Saturday. They got 25 points from Grayson Allen and beat Grand Canyon 96-61, which means the ACC favorite will enter Tuesday's game with Kansas in possession of a 2-0 record despite the fact that projected lottery picks Jayson Tatum, Harry Giles and Marques Bolden still haven't played a minute.

All three are recovering from injuries.

And Hall of Fame coach Mike Krzyzewski said Saturday that he doesn't expect any of them to play against Kansas. Consequently, it's possible the nation's No. 1 team will be an underdog to an 0-1 team Tuesday at Madison Square Garden, and that has to be rare, doesn't it? Bottom line, there could be a new No. 1 Wednesday morning. For now, though, here's the updated CBS Sports Top 25 (and one).
