I'd go with either:
(Belichick's voice...a little higher and squeakier than usual)
“What's that? Ah -- defense? Don't talk about -- defense?! You kidding me?! Defense?! I just hope we can win a game! Another game!

(Brady's voice)
"If we can't defend, we can't defend. It is as simple as that. It ain't about that at all. It's easy to sum it up if you're just talking about defense. We're sitting here, and I'm supposed to be the franchise player, and we're talking about defense. I mean listen, we're sitting here talking about defense, not a game, not a game, not a game, but we're talking about defense. Not the game that I go out there and die for and play every game last it's my last but we're talking about defense man. How silly is that?
Now I know that I'm supposed to lead by example and all that but I'm not shoving that aside like it don't mean anything. I know it's important, I honestly do but we're talking about defense. We're talking about defense man. We're talking about defense. We're talking about defense. We're not talking about the game. We're talking about defense. When you come to the arena, and you see me play, you've seen me play right, you've seen me give everything I've got, but we're talking about defense right now."
