It's actually 2, as Noah only played in 48 games this season. But I'd take Wade over Rondo, personally.
I only pointed this out to say that I don't care for the award, not to say that I don't believe Rondo is a terrific defensive player.
But ya, I do believe that Chris Paul is a slightly better defensive player than Rondo. Though, I'd concede that if Rondo truly focused and stay disciplined he'd be the better defender.
