Gonzaga was favored by -7 but as people have been saying lately, Duke is never an underdog: the Blue Devils came to Las Vegas and showed the world what Duke Basketball means with an 84-81 win. And as a result, with #1 Gonzaga, #2 UCLA and #3 Kansas all losing, the Blue Devils are going to move into the Top 3 and have a strong argument to be #1 on Monday (Baylor, and especially Purdue, will have something to say about it as well).
To an extent, although not nearly as dramatically, Duke did what Baylor did last spring: they showed they were a more athletic team than Gonzaga.
