But the Bruins (0-4, 0-1 Big Ten), despite their 17-14 loss in Evanston on Saturday afternoon, showed fight — a hunger that from the outside looking in had previously escaped the watchful eye. On defense — after a first half which exploited much of their same inequities on the field, allowing 17 points and 108 rushing yards — UCLA turned a corner, shutting out Northwestern in the second half. Martin, a redshirt sophomore transfer from Arizona State and the son of defensive backs coach Demetrice Martin, collected a career-high nine tackles and a tackle for loss. “We were just fighting, and that was the biggest thing — just to fight,” defensive back Rodrick Pleasant said when asked about what sparked the second-half defensive stand. UCLA had seven tackles for loss, more than doubling any total it had produced against Utah, UNLV and New Mexico.
