Chargers general manager Tom Telesco said Wednesday on 1090AM that Ryan Mathews remains the "bell cow" despite the addition of Donald Brown as a free agent this offseason, reports ESPN.

"We know Ryan is our bell cow," Telesco said. "He's our No. 1 back. He had an excellent year last year. And we all know what Danny Woodhead can do in his role. We saw that for 16 games last year. And we think Donald can come in and add to that, too, and give us some different options. And a different style, too. The more weapons we can have for Philip Rivers, the better."
