I'm not sure I'd even call it negative. It's taking care of the ball vs looking for breaks, playing safe yardage sets vs throwing the ball about. Both approaches have their merits, and have times when they're the right way to play and times when they're wrong.
Likewise, it's possible to play both an attacking defensive style, and a conservative defensive style.
