UCLA has won 10 straight games since losing to Arizona and USC in successive games at the end of January, playing the same fast-paced offensive style but with better defense and rebounding. The Bruins pulled out their quarterfinal win Thursday by holding USC to just 38.7 percent shooting and 36.0 percent from 3-point range. They’ve been using a mix of a 3-2 zone and man-to-man defense.
