UCLA shot 39 percent in Thursday's loss to the Longhorns. This time, the Bruins shot 58 percent in a sloppy game that featured a combined 42 turnovers for the two teams.
"I was worried about them looking at the record of their opponent and having a letdown," Howland said of his team.
Northridge (1-6) ended its longest road trip in 15 years with an 0-6 record, losing at Stanford, Cal State Bakersfield, New Mexico, Rider, Drexel and UCLA, located 15 miles from its campus. Tremaine Townsend scored a career-high 23 points for the Matadors. Kenny Daniels had career-highs with 13 points and six rebounds.
Howland used 11 players, including all of his five freshmen, and they put the game away in the first half.
"We did a very good job in the first half defensively and forced turnovers," Howland said.
UCLA quickly stretched its lead to 23 points early in the second half, helped by consecutive 3-pointers from Collison and another by Holiday.
