DURHAM – Even in a 37-point win, it was clear that top-ranked Duke misses injured point guard Kyrie Irving.

Thanks to an outstanding defense that forced 22 turnovers, the Blue Devils easily defeated Saint Louis this afternoon, 84-47, at Cameron Indoor Stadium.

But Duke (10-0) still is trying to figure out how to play on offense as Irving missed his second straight game with an injured big toe on his right foot.
