Linebacker Brian Cushing returned to Los Angeles to work on his college degree and to workout. Going back to USC to earn a degree in sociology was the easy part. Participating in a workout regimen designed for mixed martial arts by Fox insider Jay Glazer has been testing Cushing's resolve and allowing him to reach a mental and physical level he didn't know he had. ?Brian's a beast, an absolute animal,? said Glazer, who has been involved with MMA for 11 years. ?Usually, NFL players come to us in March, but Brian started the week after the Super Bowl. That shows the kind of player and person he is, the kind of determination he has. He's a cyborg.?
