a.k.a. SCORE MORE POINTS!!!
Before the season ESPNWisconsin's Jason Wilde asked McCarthy about the tweaks to the running game...
ESPN Wisconsin: You’ve said that...you’ve made some changes schematically.
McCarthy: Let me ask you something: How come no one ever asks about how many points we score?
ESPN Wisconsin: What do you mean? You led the league in scoring in 2011 and last year you were still fifth even though your kicker went through a period where he couldn’t hit the broad side of a barn.
McCarthy: I mean, isn’t it about scoring points?
He doesn't need his defense to stop the other team on every drive, just stop enough drives so that his offense can run more plays than their opponent and... SCORES MORE POINTS!!!
