New backup QB Jason Campbell indicated he's catching on to a new offense because it's similar to some he's run in the past. But his backup role is new. "I’m used to getting a lot of the reps, but now you’re the backup and everything changes a little bit," Campbell said. "Most of my thing is learning as much as I can in the classroom and trying to apply things once the season starts after practice just to keep myself involved with what’s going on.”
