Campbell is strong all around defensively. They bring an older and talented defensive line to the game with three seniors. I would watch for them and the very talented linebacker core to have a great game. The entire Camel defense has some nice speed, and I know they are coming to the game prepared. As for how well they play the run, they remain fairly untested, but they look much improved from years past in the run defense category.
To answer your question, I really don't know how much Campbell will pass, but they tend to pass the ball a bit more than they run it.
