USC reached this point by beating Drake and Kansas holding those two worthy opponents to a combined 29.2 percent shooting from the floor. It was a combination of outstanding Trojans defense and poor shooting by the Bulldogs and Jayhawks. 
I expect Oregon to shoot much better than those teams. I like the Ducks' ability to adapt and follow Dana Altman's tremendous coaching. 
The Ducks have shot 52 percent, or better, in five of their last seven games. They surprised Iowa, 95-80, by playing extremely fast. Oregon has the Pac-12's most efficient offense and also ranked No. 1 in 3-point percentage. The Hawkeyes seemed caught by surprise how well the Ducks played in transition. The Ducks hit 11 3-pointers against Iowa. Oregon is now 15-1 when making at least eight 3-point shots. USC ranks 173rd in 3-point defense. 
The Trojans hold a rebounding edge with their tremendous size. USC defeated Oregon, 72-58, at home on Feb. 22. That was a rare late-season defeat for Oregon, which is 13-2 in its last 15 games. 
I'm sure the astute Altman learned from that earlier loss to USC. The Ducks have the flexibility to play various effective styles of zone defenses and to also employ a deadly full court press. They can play fast or slow with equal efficiency. Oregon also has the outside shooting prowess to offset USC's size advantage. 
Oregon holds a free throw edge, too. The Ducks make 71.2 percent of their free throws. USC was the worst free throwing shooting team in the Pac-12 at 64.3 percent. 
The Ducks have reached the regional semifinal in four of the past five tournaments. They have covered 10 of the last 11 times they've been a 'dog in NCAA Tourney action. USC hasn't reached the Sweet 16 since 2007.
