UCLA offensive coordinator Noel Mazzone talked on Wednesday about freshman receiver Mossi Johnson, running back Paul Perkins’ pass-catching — and finally, the Bruins’ recent spate of turnovers.

The team has lost 10 turnovers this season, coughing up five of them against Oregon and Cal.

“It’s like that thing you don’t talk about, right?” Mazzone said. “Hope it goes away? Protecting the football, it’s all about the ball. … Over the past two weeks, that’s something that’s hit us.”
