A Stats Thread: What the Numbers Say About Rondo and Gay

Has anyone ever stopped to think that maybe Rondo didn't play defense because George Karl never held his players accountable on that end of the court?

Rondo used to be one of the most tenacious defenders in the NBA.

Now that Rondo is back to full health, there is nothing that says he can't be an effective defender when properly motivated by the coach and his system.
He didn't play defense at the end in Boston or in Dallas either.
